Ambler Arboretum of Temple University

Posted By Admin, Friday, May 12, 2023

Dedicated in 2010 and donated by the Colibraro family, the exquisite conifer cultivars in the Colibraro Conifer Garden create a unique teaching garden.

The garden, located in the Greenhouse Education and Research Complex, includes exquisite dwarf conifer cultivars. Adding to the special nature of this collection, the garden is surrounded by full-sized examples of some of the dwarf conifers found within,giving a unique opportunity for visitors and students alike to compare options for uses in various landscape situations.

For over 50 years, Colibraro Landscaping & Nursery, Inc., a family-owned and operated design/build firm located in Horsham,has served Bucks County and Montgomery County.The Colibraro family have been dedicated supporters of the Ambler Arboretum of Temple University for decades.

Update, October 2021, from Kathy Salisbury, Director, Ambler Arboretum of Temple University:

Originally, this report was supposed to be one updating the American Conifer Society on the progress and activities of the Arboretum as it relates to our recently awarded reference garden status.

Quickly, overnight, this changed. On Sept 1, 2021 a confirmed EF2 tornado, spawned by the remnants of Hurricane Ida, tore through the Temple University Ambler Campus, Ambler Field Station and the Ambler Arboretum.

First – the Colibraro Conifer Garden looks nearly untouched. We have the most perfect Eastern Red cedar which was tipped up in the storm and we lost our limber pine (Pinus flexilis) but other than that our reference garden still looks great!

We cannot say the same for other conifers around the campus and the canopy and collection in general. This storm was a devastating loss to the Arboretum. Hundreds of trees are lots. In some places we lost the entire canopy. Our old growth forest, consisting of trees hundreds of years old were reduced to pick up sticks littering the floor. A shadow of their former selves, those trees standing are not only leafless but branchless.

Our conifers suffered. The Arboretum featured dozens of very mature white pines dotted all over the campus, now just a few remain. Towering Norway Spruces and Oriental Spruces shaded walkways and screened views of our high traffic work yards.

Our only two Himalayan Pines, giants in the landscape were snapped in half. Our Pinetum lost some of the Japanese Black Pines as well as White Pines. The Scots Pine still stands tall.

The smaller conifers around the Arboretum fared better, though we did lose a number of various Chamaecyparis specimens.

Our immense Blue Atlas Cedar and graceful weeping Norway Spruce still greet visitors and are there to teach students when the time is right.

Tis was a sad blow to the Arboretum. Each tree is connected in ways we may never know to the humans that use this campus. The Arboretum is changed forever and though we grieve what was, and the long lives those old trees still had ahead of them, we are optimistic and excited about what can become of these new spaces so full of opportunity.

We are currently still working on clean up and recovery. There was a lot of damage in addition to the plants we lost. But we are seeing the nearing of the end of the response and looking at the beginning of planning what’s next. We certainly know landscaping about climate change and resilience will be at the top of the list.

Wellesley College Botanic Gardens

Posted By Admin, Friday, May 5, 2023

Henry and Pauline Durant, the founders of Wellesley College in 1875, were committed to the liberal arts education of women and by the 1890's the school's curriculum was revised to include study of all the major sciences and the development of state-of-the-art laboratory experiences for its students. In 1920, Dr. Margaret Ferguson, Chair of the Department of Botany, initiated the construction of the greenhouses (now the Margaret Ferguson Greenhouses) and requested that over 20 acres of campus (that had formerly been a golf course for students) be set aside for exclusive use of the Botany Department.

In collaboration with Dr. Helen Davis, also in the Botany Department, they eschewed the beaux-arts design that landscape architect Arthur Shurtleff had deployed elsewhere on campus and laid out a more naturalistic design that included an artificial waterfall, a stream with intermittent small pools and a terminal pool, along with open fields, bog, bird habitat, wildflower garden, rock garden, scree, azalea hill and woodland garden. Plantings contained a representation of as many of the plant families as possible to allow students to compare similarities and differences among genera and species.

The Conifer Reference Garden

With the arrival of a new Director of the Botanic Gardens and Greenhouse in 2005, Dr. Kristina Jones, there has been a revision of the plantings. The Educational Garden, which contains the Conifer Reference Garden, was one of the first major changes. A perennial and weed infested embankment along the drive approaching the Greenhouses (Fig. 1) was designated the site of the Creighton Educational Garden in memory of Harriet Creighton, Professor of Botany from 1940 to 1974. Dr. Creighton's focus had always been botanical education so this was an appropriate memorial. Dr. Mary Coyne, Professor Emerita of Biological Sciences, who also has a Certificate in Landscape Design drew up the original design (Fig. 2). The gardens were set off by a fieldstone wall and steps leading to the Botanic Gardens proper and included a conifer garden, butterfly garden, rock garden and scree, replacing garden areas that had been lost from the original Botanic Garden design (Fig. 3).

Because of the defined space, the conifer garden was limited to dwarf and miniature specimens as well as some prostrate forms of standard species. Dr. Coyne, who knew nothing about conifers, spent the winter after construction pouring through books and websites to pick representative conifers that would display differences in leaf structure, shape, and color including changes in color and leaf retention over the winter. Two knowledgeable and long-standing members of the American Conifer Society, Gerald Kral and Elmer Dustman, vetted the final choices.

The wall was built in August 2006 of field stones and capped with a bluestone. The stairs were designed to provide seating along the wall and a space for people to aggregate at the beginning of tours (Fig 4). It has also become a popular luncheon spot. The planting area was layered with large sitting rocks that were located near the butterfly garden and the remaining stones were carefully placed throughout the conifer area with a larger accumulation in the alpine scree. Rock garden plants would be placed around the stones to complement the conifers.

The conifers were planted in the spring of 2007 and were distributed throughout the entire garden area to maintain winter interest. Most of the plantings have survived well except for Picea planted in the scree. The Harriet Creighton Botanic Garden Fund and the Friends of Horticulture paid for the wall; initial conifer specimens were supported by the plant budget for the Wellesley College Botanic Gardens, but there were still items that were needed.

In winter of 2008, the American Conifer Society recognized the area as a Conifer Reference Garden and we requested and received funds for a drip irrigation system, commercial labels, additional and replacement plants, student help in maintenance, and publicity materials. Each section of the garden contains a sign with information and a QR code which directs the visitor to more information on the Wellesley College Botanic Gardens website. We are also beginning to experiment with the use of conifers in troughs and our initial trough is displayed in the Cameron Garden across the way next to the Greenhouses.

The Frelinghuysen Arboretum

Posted By Admin, Thursday, May 4, 2023
The Frelinghuysen Arboretum, a property of 124 acres that was originally the private summer estate of George and Sara Frelinghuysen and known as “Whippany Farm”, became a facility of the Morris County Park Commission (MCPC) in 1969. It serves the public as a resource for horticultural displays, educational horticulture programming, and community events. The Colonial Revival mansion was built in 1891 and the historic estate landscape has been preserved within the core area near the mansion. The site features a large variety of display gardens, woodland walking trails, and a Pinetum.

The conifers at the Frelinghuysen Arboretum are spread throughout the gardens, but the largest concentration is in the Pinetum area in the southwest corner of the property. The Pinetum can be accessed from trails at the right rear of the parking lot, or from paths descending behind the mansion. Lovely walking trails make a circular loop through the woods and meadow, with regular benches to rest and enjoy the views.

Many of the oldest specimens at the Frelinghuysen Arboretum date to the early 1900’s after the Frelinghuysen’s bought the property and constructed the mansion as their summer home. Some plants, such as the large Cedrus atlantica ‘Glauca’ in front of the mansion, can be identified in old family photographs in the MCPC archives. Matilda Frelinghuysen planned for the site’s transition into an arboretum, in memory of her father, when the property was donated to the MCPC in 1969. Since the property’s transition into the park system, a visitor center (the Haggerty Education Center) has been built and new plantings installed throughout the site. Additional conifers were planted in the gardens around the education center, in the Pinetum, and in the gardens between the parking lot bays.

Currently, as of August 2021, there are 527 total conifers representing 52 individual species and 112 different cultivars and varieties. The collection includes many unusual specimens and some champion trees--the largest of their kind in New Jersey. Each tree is tagged with a black plastic label that gives its botanical name, common name, family group, and origin. The plant records are maintained in IrisBG, a database designed for botanical collections. The plant records are an important resource for developing maps and tours of the conifer collection at the Frelinghuysen Arboretum.

Soon after the property was donated to the MCPC, a group of dedicated volunteers established the Friends of The Frelinghuysen Arboretum. The Friends are proud to partner with the MCPC to support the arboretum, and to attract area residents who learn to appreciate horticulture and the natural world through a range of educational programs.

Tanger Arboretum

Posted By Admin, Thursday, May 4, 2023
The Tanger Arboretum was built on the grounds of the Wilson Memorial building home to Lancaster history. org. beginning in 1956. The founder Louise Arnold Tanger worked on the garden until her death in 1959 at which time her son Charles continued the work until he died in 1991. The board then established a friends group to maintain the garden. A master landscaping plan was designed, tree labels were added, and a map developed for self-guided tours.

In late 2015, an American Conifer Society (ACS) Reference Garden was added to the Tanger Arboretum. This reference garden, also referred to as the Dwarf Conifer Garden, contains 150 species of dwarf and miniature conifers and the collection continues to grow.

The Tanger Arboretum is open from dawn to dusk to the public. There is no admission fee. Maps of the Arboretum and the Dwarf Conifer Reference Garden are available at Visitor Services at Lancaster History, Monday – Saturday 9:30am – 5pm.

View the dwarf conifer collection

Mary (Polly) Wakefield created the gardens and the arboretum of the Wakefield Estate over a 40 year period. When Polly passed away in 2004, she left her 22-acre property in a private trust to be used for education and community enjoyment. A trained landscape designer and horticulturalist, Polly created formal gardens, plant nurseries, woodland trails, and planted wetlands, growing much of the plant material from seed or cuttings. She worked closely with the Arnold Arboretum of Harvard University to develop her collection. The gardens most important feature is more than 300 Cornus kousa dogwoods, all originating from the same seed source at the Arnold Arboretum. Polly also planted many varieties of maples, magnolias, and conifers.

In 2017, the Mary May Binney Wakefield Arboretum became an Arbnet Class II certified arboretum and was listed on the National Register of Historic Places. The gardens have been lovingly restored with careful pruning, the addition of new plant material, and unique hardscape features.

The dwarf conifer garden was added to the collection in the summer of 2018. This garden currently boasts more than 30 dwarf conifer varieties surrounded by many gardens with a broad range of full-size conifers planted with other species. The dwarf conifers were selected for hardiness and year-round display. Polly Wakefield worked with Arnold Arboretum plant propagator Al Fordham, a pioneer in work with dwarf conifers and began experimenting with dwarf species herself in the late 1970's and later creating her “witches garden with dragon gate”. Several of her dwarf conifers remain in the gardens today.

Open hours: The Wakefield Estate welcomes visitors to tour the property during regular business hours (9-4 Mon-Fri). In addition, the estate is open on weekends for special events or by appointment (see our website: wakefieldtrust.org for event listings). To arrange "by appointment", visits please call 617-333-0924 x22.

Draves Arboretum

Posted By Admin, Wednesday, May 3, 2023

Draves Arboretum is located in rural Western New York. The 20 acre property consists of several themed areas including ‘The Pinetum,’ four acres dedicated to the collection and study of conifers. Additionally, groups of conifers are intermingled with other woody specimens throughout the facility. An additional area has been chosen for a distinct miniature and dwarf conifer section to be developed in 2021.

Curator and President, Thomas Draves and his family began the diverse collection 25 years ago. Through subsequent years, the collection has grown to include over 800 species of woody plants, and currently includes almost 100 conifer species consisting of 274 plants. Species can be observed at all stages of maturity, with detailed attention given to accessible labelling for identification and educational purposes.

Draves Arboretum acquired its Level II accreditation from ArbNet in 2018, and in 2019 received advanced accreditation as a Level III Arboretum, becoming one of only twenty-eight with this distinction worldwide.

As the collection gained regional notoriety, the arboretum became Provisionally Chartered by the Regents of the University of the State of New York, evolving into a center for public education. Draves Arboretum offers courses for professionals within the green industry, programs for local colleges, private tours, and classes for garden clubs and other organized groups.

Visitors and groups are welcome daily by appointment: 585-547-3341

Bayard Cutting Arboretum

Bayard Cutting Arboretum

Bayard Cutting Arboretum Facebook page


Bayard Cutting Arboretum (BCA) is a 691-acre tract in Great River, NY, along the Connetquot River on the south shore of Long Island. The property, constructed in 1886, was originally owned by Mr. William Bayard Cutting and his family. Mr. Cutting saw potential in the natural beauty of the surrounding landscape, and, utilizing plans developed by the noted landscape architecture firm of Frederick Law Olmsted, began the arboretum in 1887.

BCA is home to many unique specimens, extensive collections of oaks, hollies and rhododendrons, and expansive native woodlands. However, the most notable collections are those including conifers. Mr. Cutting began to plant his conifer collection in the late 1800s, with the support of Dr. Charles Sprague Sargent, then Director of Harvard’s Arnold Arboretum in Massachusetts. Mr. Cutting had an affinity for firs and spruces because of their kempt and conical habits, in contrast to what he saw as the unruly appearance of pines. He appreciated rare specimens that could grow both in his backyard and across the world. Some of his original plantings can be seen today in the heart of the Bayard Cutting Arboretum, the Old Pinetum...See full article.
