The Arnold Arboretum of Harvard University is an arboretum located in the Jamaica Plain and Roslindale sections of Boston, Massachusetts. It was designed by Frederick Law Olmsted and is the second largest "link" in the Emerald Necklace.


The Arboretum was founded in 1872 when the President and Fellows of Harvard College became trustees of a portion of the estate of James Arnold (1781–1868).

In 1842, Benjamin Bussey (1757–1842), a prosperous Boston merchant and scientific farmer, donated his country estate Woodland Hill and a part of his fortune to Harvard University "for instruction in agriculture, horticulture, and related subjects". Bussey had inherited land from fellow patriot Eleazer Weld in 1800 and further enlarged his large estate between 1806 and 1837 by acquiring and consolidating various farms that had been established as early as the seventeenth century. Harvard used this land for the creation of the Bussey Institute, which was dedicated to agricultural experimentation. The first Bussey Institute building was completed in 1871 and served as headquarters for an undergraduate school of agriculture.

Sixteen years after Bussey’s death, James Arnold, a New Bedford, Massachusetts whaling merchant, specified that a portion of his estate was to be used for "…the promotion of Agricultural, or Horticultural improvements". In 1872, when the trustees of the will of James Arnold transferred his estate to Harvard University, Arnold’s gift was combined with 120 acres (0.49 km2) of the former Bussey estate to create the Arnold Arboretum. In the deed of trust between the Arnold trustees and the College, income from Arnold’s legacy was to be used for establishing, developing and maintaining an arboretum to be known as the Arnold Arboretum which "shall contain, as far as practicable, all the trees [and] shrubs … either indigenous or exotic, which can be raised in the open air of West Roxbury". The historical mission of the Arnold Arboretum is to increase knowledge of woody plants through research and to disseminate this knowledge through education.

Charles Sprague Sargent was appointed director and Arnold Professor of Botany shortly after the establishment of the institution in 1872.[2] Together with landscape architect Frederick Law Olmsted he developed the road and pathway system and delineated the collection areas by family and genus, following the then current and widely accepted classification system of Bentham and Hooker. The Hunnewell building was designed by architect Alexander Wadsworth Longfellow, Jr. in 1892 and constructed with funds donated by H. H. Hunnewell in 1903. From 1946 to 1950 the landscape architect Beatrix Farrand was the landscape design consultant for the Arboretum. Her early training in the 1890s included time with Charles Sprague Sargent and chief propagator and superintendent Jackson Thornton Johnson.[3] Today the Arboretum occupies 265 acres (107 hectares) of land divided between four parcels, viz. the main Arboretum and the Peters Hill, Weld-Walter and South Street tracts. The collections, however, are located primarily in the main Arboretum and on the Peters Hill tract. The Arboretum remains one of the finest examples of a landscape designed by Frederick Law Olmsted and it is a Frederick Law Olmsted National Historic Site) and a National Historic Landmark.

Robert E. Cook is the seventh and current Director of the Arnold Arboretum. He is also the Director of the Harvard University Herbaria located in Cambridge, Massachusetts.


The Arboretum is privately endowed as a department of Harvard University. The land, however, was deeded to the City of Boston in 1882 and incorporated into the so-called "Emerald Necklace". Under the agreement with the City, Harvard University was given a thousand-year lease on the property, and the University, as trustee, is directly responsible for the development, maintenance, and operation of the Arboretum; the City retains responsibility for water fountains, benches, roads, boundaries, and policing. The annual operating budget of $7,350,644 (fiscal year 2003) is largely derived from endowment, which is also managed by the University, and all Arboretum staff are University employees. Other income is obtained through granting agencies and contributors.


The main Arborway gate is located on Route 203 a few hundred yards south of its junction with the Jamaicaway. Public transportation to the Arboretum is available on the MBTA Orange Line to its terminus at Forest Hills Station and by bus (#39) to the Monument in Jamaica Plain. The Arboretum is within easy walking distance from either of these points.


The grounds are open free of charge to the public from sunrise to sunset 365 days of the year. The Visitor’s Center in the Hunnewell Building, 125 Arborway, is open Monday through Friday 9 a.m.–4 p.m.; Saturdays 10 a.m.–4 p.m.; Sundays 12 p.m.–4 PM. The Visitor’s Center is closed on holidays. The Library, located in the Hunnewell Building, is open Monday through Saturday, 10 a.m.–4 p.m.. The Library is closed on Sundays and holidays. Stacks are closed and the collection does not circulate.


Two hundred and sixty-five acres (107 hectares) in the Jamaica Plain and Roslindale sections of Boston, Massachusetts, located at 42°19′N 71°5′W / 42.317°N 71.083°W / 42.317; -71.083, with altitudes ranging from 46 feet (15 m) in the meadow across the drive from the Hunnewell Building to 240 feet (79 m) at the top of Peters Hill.


Average yearly rainfall is 43.63 inches (1,102 mm); average snowfall, 40.2 inches (102 centimeters). Monthly mean temperature is 51.5 °F (10.8 °C); July’s mean temperature is 73.5 °F (23 °C); January’s is 29.6 °F (-1.3 °C). The Arboretum is located in USDA hardiness zone 6 (0 to −10 °F, −18 to −23 °C).

Collections (as of September 14, 2007)

At present, the living collections include 15,441 individual plants (including nursery holdings) belonging to 10,216 accessions representing 4,099 taxa; with particular emphasis on the ligneous species of North America and eastern Asia. Historic collections include the plant introductions from eastern Asia made by Charles Sprague Sargent, Ernest Henry Wilson, William Purdom, Joseph Hers, and Joseph Rock. Recent introductions from Asia have resulted from the 1977 Arnold Arboretum Expedition to Japan and Korea, the 1980 Sino-American Botanical Expedition to western Hubei Province, and more recent expeditions to China and Taiwan.

Comprehensive collections are maintained and augmented for most genera, and genera that have received particular emphasis include: Acer, Fagus, Carya, Forsythia, Taxodium, Pinus, Metasequoia, Lonicera, Magnolia, Malus, Quercus, Rhododendron, Syringa, Paulownia, Albizia, Ilex, Gleditsia and Tsuga. Other comprehensive collections include the Bradley Collection of Rosaceous Plants, the collection of conifers and dwarf conifers, and the Larz Anderson Bonsai Collection. Approximately 500 accessions are processed annually.

Collections policy

The mission of the Arnold Arboretum is to increase our knowledge of the evolution and biology of woody plants. Historically, this research has investigated the global distribution and evolutionary history of trees, shrubs and vines, with particular emphasis on the disjunct species of East Asia and North America. Today this work continues through molecular studies of the evolution and biogeography of the floras of temperate Asia, North America and Europe.

Research activities include molecular studies of gene evolution, investigations of plant-water relations, and the monitoring of plant phenology, vegetation succession, nutrient cycling and other factors that inform studies of environmental change. Applied work in horticulture uses the collections for studies in plant propagation, plant introduction, and environmental management. This diversity of scientific investigation is founded in a continuing commitment to acquire, grow, and document the recognized species and infraspecific taxa of ligneous plants of the Northern Hemisphere that are able to withstand the climate of the Arboretum’s 265-acre (1.07 km2) Jamaica Plain/Roslindale site.

As a primary resource for research in plant biology, the Arboretum’s living collections are actively developed, curated, and managed to support scientific investigation and study. To this end, acquisition policies place priority on obtaining plants that are genetically representative of documented wild populations. For each taxon, the Arnold Arboretum aspires to grow multiple accessions of known wild provenance in order to represent significant variation that may occur across the geographic range of the species. Accessions of garden or cultivated provenance are also acquired as governed by the collections policies herein.

For all specimens, full documentation of both provenance and history within the collection is a critical priority. Curatorial procedures provide for complete and accurate records for each accession, and document original provenance, locations in the collections, and changes in botanical identity. Herbarium specimens, DNA materials, and digital images are gathered for the collection and maintained in Arboretum data systems and the herbarium at the Roslindale site.


Research on plant pathology and integrated pest management for maintenance of the living collections is constantly ongoing. Herbarium-based research focuses on the systematics and biodiversity of both temperate and tropical Asian forests, as well as the ecology and potential for sustainable use of their resources. The Arboretum’s education programs offer school groups and the general public a wide range of lectures, courses, and walks focusing on the ecology and cultivation of plants. Its quarterly magazine, Arnoldia, provides in-depth information on horticulture, botany, and garden history. Current Research Initiatives

Plant Records

Plant records are maintained on a computerized database, BG-BASE 6.8 (BG-Base Inc.), which was initiated in 1985 at the request of the Arnold Arboretum and the Threatened Plants Unit (TPU) of the World Conservation Monitoring Centre (WCMC). A computerized mapping program (based on AutoCAD (Autodesk)) is linked to BG-BASE, and each accession is recorded on a series of maps at a scale of 1-inch (25 mm) to 20 feet (1:240) or 1-inch (25 mm) to 10 feet (1:120). A computer-driven embosser generates records labels. All accessioned plants in the collections are labeled with accession number, botanical name, and cultivar name (when appropriate), source information, common name, and map location. Trunk and/or display labels are also hung on many accessions and include botanical and common names and nativity. Stake labels are used to identify plants located in the Leventritt Garden and Chinese Path.

Grounds Maintenance

The grounds staff consists of the superintendent and assistant superintendent, three arborists, and ten horticultural technologists. A service garage is adjacent to the Hunnewell Building, where offices and locker rooms are located. During the summer months ten horticultural interns supplement the grounds staff. A wide array of vehicles and modern equipment, including an aerial lift truck and a John Deere backhoe and front loader, are used in grounds maintenance. Permanent grounds staff, excluding the superintendents, are members of AFL/CIO Local 615, Service Employees International Union (SEIU).

Nursery and Greenhouse Facilities

The Dana Greenhouses, located at 1050 Centre Street (with a mailing address of 125 Arborway), were completed in 1962. They comprise four service greenhouses totaling 3,744 square feet (348 m²), the headhouse with offices, cold rooms, storage areas, and a classroom. Staffing at the greenhouse includes the manager of greenhouses and nurseries, the plant propagator, two assistants, and, during the summer months, two horticultural interns. Adjacent to the greenhouse is a shade house of 3,150 square feet (293 m²), a 12,600 cubic foot (357 m³) cold storage facility, and three irrigated, inground nurseries totaling approximately one and one-half acres (6,000 m²). Also located in the greenhouse complex is the bonsai pavilion, where the Larz Anderson Bonsai Collection is displayed from the middle of April to the end of October. During the winter months the bonsai are held in the cold storage unit at temperatures slightly above freezing.

Isabella Welles Hunnewell Internship Program

The living collections department of the Arnold Arboretum offers a paid summer internship program [2] that combines hands-on training in horticulture with educational courses. Intern trainees will be accepted for 12- to 24-week appointments. Ten interns will work with the grounds maintenance department and two in the Dana Greenhouses.

As part of the training program, interns participate in mandatory instructional sessions and field trips in order to develop a broader sense of the Arboretum’s horticultural practices as well as those of other institutions. Sessions and field trips are led by Arnold staff members and embrace an open question and answer format encouraging all to participate. Interns often bring experience and knowledge that everyone, including staff, benefits from. It is a competitive-free learning environment.

Horticultural Apprenticeship

The Arboretum created the horticultural apprenticeship program in 1997 to provide hands-on experience in all aspects of the development, curation, and maintenance of the Arboretum’s living collections to individuals interested in pursuing a career in an arboretum or botanical garden.

The Living Collections department of the Arnold Arboretum offers a summer internship program[4] that combines practical hands-on training in horticulture with educational courses. Fourteen Interns/Horticultural Trainees are accepted for twelve to twenty-four week appointments. Interns receive the majority of their training in one of three departments: Grounds Maintenance, Nursery and Greenhouse, or Plant Records.

Lilac Sunday

The second Sunday in May every year is "Lilac Sunday". This is the only day of the year that picnicing is allowed. In 2008, on the 100th anniversary of Lilac Sunday, the Arboretum website touted:

Of the thousands of flowering plants in the Arboretum, only one, the lilac, is singled out each year for a daylong celebration. On Lilac Sunday, garden enthusiasts from all over New England gather at the Arboretum to picnic, watch Morris dancing, and tour the lilac collection. On the day of the event, which takes place rain or shine, the Arboretum is open as usual from dawn to dusk.[5]

Associated Collections

The Arboretum’s herbarium in Jamaica Plain holds specimens of cultivated plants that relate to the living collections (ca. 160,000). The Jamaica Plain herbarium, horticultural library, archives, and photographs are maintained in the Hunnewell building at 125 Arborway; however, the main portions of the herbarium and library collections are housed in Cambridge on the campus of Harvard University, at 22 Divinity Avenue.


The inventory of living collections is updated periodically and made available to sister botanical gardens and arboreta on request; it is also available on the Arboretum’s website (searchable inventory). Arnoldia, the quarterly magazine of the Arnold Arboretum, frequently publishes articles relating to the living collections. A Reunion of Trees[6] by Stephen A. Spongberg (curator emeritus) recounts the history of the introduction of many of the exotic species included in the Arobretum’s collections. New England Natives[7] written by horticultural research archivist Sheila Connor describes many of the trees and shrubs of the New England flora and the ways New Englanders have used them since prehistoric times. Science in the Pleasure Ground[8] by Ida Hay (former curatorial associate) constitutes an institutional biography of the Arboretum.

Institutional Collaborations

The Arboretum maintains an institutional membership in the American Public Garden Association (APGA) and the International Association of Botanical Gardens and Arboreta. Additionally, members of the staff are associated with many national and international botanical and horticultural organizations. The Arboretum is also a cooperating institution with the Center for Plant Conservation (CPC), and as an active member of the North American Plant Collections Consortium (NAPCC), it is committed to broadening and maintaining its holdings of: Acer, Carya, Fagus, Stewartia, Syringa, and Tsuga for the purposes of plant conservation, evaluation, and research. The Arboretum is also a member of the North American China Plant Exploration Consortium (NACPEC).

    In case if you are wondering what bare drive inside, September 13, 2016

    Verified Purchase(What’s this?)

    This review is from: Seagate Backup Plus Hub 8TB External Desktop Hard Drive Storage + 2mo Adobe CC Photography (STEL8000100) (Personal Computers)

    UPDATE-2: After Christopher K.’s feedback I conducted further tests to isolate that “cyclical head activity” situation.
    I first unplugged CAT6 cable to my NAS (Synology DiskStation DS213air). Wi-fi is already disabled. So NAS become absolutely stand-alone, away from all external interaction. When you unplug the ethernet cable, it goes thru a busy few minutes with disk activitiy. Then after it “calmed down”, I noticed that such semi-cyclical head activity is still going on. At that point the only possible intervention to drives can obviously be coming from NAS operating system (DSM 6.1.3-15152 Update 3) and/or these 3 “packages” running on that NAS OS:
    -Universal Search (can’t disable)
    -File Station (can’t disable)
    -Media Server (can uninstall)
    So in theory either NAS OS or one of these packages can be “polling” the drives cyclically. Otherwise, such cyclical activity must be coming from drive itself. I checked a bit more online for that ST8000AS0002 drive. Looks like Seagate part no is 1NA17Z and firmware version of my drives is: RT17 . Seagate website informs that; “No Newer Firmware Available / A field update is not available” (I guess they don’t want to give users the ability to change firmware – potentially discovering built-in “NSA code”! (as discovered by Kaspersky few years ago)).
    Since user Christopher K. reported silent NAS operation of his same drives; the chances are that they might have never firmware. Or it could be purely because of NAS OS.
    I update both OS and packages on my Synology NAS as they become available. So it might be theoretically possible that one such update (which coincided with me installing these new Seagate drives) could be the reason behind such cyclical activity. But I noticed this nuisance immediately after upgrading to these new Seagate drives. So I still reasonably think that it’s being caused by the drive itself (whether SMR structure or firmware level).

    On my test, next I plugged back CAT6 cable to my NAS. So now it’s hardwired to my router (Netgear Nighthawk R6700); another potential source of external polling to the drives. Again after few more minutes of “calming down”; already existing activity level of drives didn’t change. So the router is not guilty.
    At that point my hard-wired desktop PCs are off. I turned on one of my Win10 PCs (running Kaspersky Internet Suite); still same activity level on those Seagate drives.

    So my conclusion is; I still think that these drives (at least the ones I have – with potentially earlier firmware) are not able to “sit quite” in my given NAS. The only absolute proof will be when I upgrade them in the future (it’ll be a non-SMR drive). If the new drives will be as quite as my earlier (non-SMR) Seagate drives; then I’ll know that the reason was those drives after all…
    UPDATE: In my NAS; drive heads seek in irregular intervals (about every 5-15 seconds), even there is no user read/write activity going on. Drives might be refreshing their buffers or something. Previous Seagate models (non-SMR type) were not doing that.
    Other than that extremely audible nuisance, this non-stop mechanical activity might shorten life-span of drives. I’ll update if they fail prematurely. I suggest that you avoid this (and any) drive that uses SMR technology.
    Inside the unit is a Seagate Archive HDD v2 ST8000AS0002 8TB 5900 RPM 128MB Cache SATA 6.0Gb/s 3.5″ Internal Hard Drive.
    I needed the internal drive. This external unit was cheaper than buying the bare drive. Plus I have an extra USB3-to-SATA board with power adapter.
    This drive uses SMR technology; so it’s supposed to be slow (not to be used as system drive – for archive purposes only).
    I replaced one of my aged NAS drives (also a Seagate 4TB Barracuda ST4000DM000 which reliably served me about 4 years – 24 hrs) with this new ST8000AS0002. Both drives have 5900 rpm speed. New one uses SMR technology, old one does not. New one runs at 100 F temperature (measured by my NAS) – old one at 90 F side-by side in NAS enclosure (fan cooled).
    I use my NAS strictly with ethernet cable (although it has wi-fi option; it’s a joke and I disabled it after trying it once). So with old drives (in parallel writing RAID mode) I was getting 75MB/sec transfer speed. Surprisingly with one new drive (other 4TB still keeps running after 4 years) I still get the same speed. So speed of this 8TB SMR drive is totally acceptable to me. Much more than archiving speed, I can consistently stream HD movie with that 75MB/sec hard-wired ethernet connection.
    For those who are thinking about doing the same; opening the case is pretty much…

    Seagate Unit and Warranty POOR, August 29, 2017

    By Finny

    Verified Purchase(What’s this?)

    This review is from: Seagate Backup Plus Hub for Mac 8TB External Desktop Hard Drive + 2mo Adobe CC Photography (STEM8000400) (Personal Computers)

    I know one can get a “lemon” sometimes, but how Seagate’s customer service dealt with the matter left me discouraged. Seagate states they provide a 2 year warranty, but let me share with you my experience in dealing with the dead drive covered by support/warranty … The product was purchased about 90 days ago, but was not used for several weeks; and thereafter, usage was light (for example, Time Machine backups for a couple laptops). Then after about 2 months of use it died last week. I attempted to locate another adapter to confirm that the adaptor was not the issue, but was unable to locate the unique one that comes with this unit (Seagate power supply: 12V 3A / barrel outside 5.5mm inside 2.5mm center positive). Therefore, I contacted customer service regarding the matter and they asked me to purchase one to test their drive. Yes, they wouldn’t send me a replacement adaptor to test their product, but rather wanted me to purchase one. So with that support interaction, I elected to return the unit under their product warranty coverage. That is when I was informed that they only warranty the product and DO NOT cover sending the product back to them to replace. And BTW, their warranty replacement unit will be a refurbished unit, not a new one … another surprise in warranty coverage. Today I mailed the drive to Seagate, and my wallet is another $20+ dollars lighter … YIKES. Therefore, due to the experience of the unit’s life (60 days with light usage) and Seagate’s support/warranty, I have to rate this product a ZERO!

    Plusses and minuses of SMR drives (with August 2018 update), October 10, 2016

    By Sanpete (in Utah) –

    This review is from: Seagate Backup Plus Hub 6TB External Desktop Hard Drive Storage + 2mo Adobe CC Photography (STEL6000100) (Personal Computers)

    Vine Customer Review of Free Product (What’s this?)

    Update, August 2018

    I’ve been using this for a year and a half to back up my Mac hourly with Time Machine. No problems at all, still works (and sounds, thumpety thump) like it has from the start.

    Original review

    The Backup Plus Hub series appears to consist of SMR (Shingled Magnetic Recording) drives. We know the 8 TB version is SMR because another reviewer (Pacific coast) opened it up (voiding his warranty) and found a Seagate Archive drive, which is SMR. I asked Seagate if the 6 TB version I got is an SMR drive, and they said “Unfortunately, we do not have this information available.” Ha ha! Their reticence is understandable, the more common PMR (Perpendicular Magnetic Recording) technology is generally preferred. The prices of these Backup Plus Hub drives are less than Seagate’s bare PMR drives of equal capacity, which also supports the idea that the Backup Plus Hub series is SMR.

    SMR technology allows more physical bits of memory in the same space without decreasing the size of the bits.

    Advantages of SMR

    — Fast burst sequential writes are possible due to higher density and allied technology.
    — Larger drive capacities in same-size enclosures.
    — Cheaper to produce in large capacities.

    Disadvantages of SMR

    — Slower random writes. SMR drives use large write heads relative to the width of the tracks of bits, so writing one track affects the next tracks of bits too. This limits SMR drives to sequential writing, where the next tracks don’t matter. To do random writes (such as changes to data on the drive already), data must be arranged sequentially in cache, by the drive in this case, and entire sections of the drive must be rewritten sequentially. Some of this can be hidden by the use of large cache on the drive, believed to be 20 GB or more on Seagate SMR drives. Data can be written quickly to cache and then rewritten more slowly to another part of the drive.
    — Highly variable sequential write speeds, due to the particular ways the drive manages where to put data.

    Read speeds aren’t affected as much.

    The consensus about SMR drives is that they’re well suited to backup use, which is reflected in the name of this series of drives. They probably aren’t as suitable to use as a main drive to run a computer from, and are generally *not* recommended for RAID configurations (which wouldn’t be likely uses for a single external drive anyway).

    Real-life speeds

    The 6 TB version of this drive hasn’t been tested by professional reviewers, but the 8 TB version has tested very well in standard benchmarks in numerous professional reviews, often well over the 160 MBs maximum rate claimed by Seagate. It’s been more variable in practical use. I’m unable to test it myself with a USB 3.0 connection, but one professional reviewer who did got an average of 72 MB/s for a write of a little under 90 GB of files. That’s a little over 20 minutes. (A customer review here–Pacific coast again–gets a similar 75 MB/s.)

    Differences between Windows and Mac versions

    According to Seagate, the only differences between this Windows version and the Mac version of the Backup Plus Hub series are the initial formatting of the drives and the cosmetics of the cases. The formatting can easily be changed at home, so buy whichever drive you please for either OS.

    System requirements

    — Windows 7 or later
    — Mac OS 10.7 or later
    — for Mobile Backup app: iOS 8 or higher, Android 3.0 or higher

    Other points

    — Doesn’t run too hot. I’ve seen measured temps of 100 and 113 degrees inside, which is fine for a hard drive.
    — A little noisy when operating, not any worse than most computers.
    — No fan, has passive cooling through vents on the bottom.
    — Includes USB 3 (or 2) cable, type A to micro-B.
    — 2-year warranty.
