• Torreya Guardians planting site at Plymouth - Seedlings were planted at the home of Joe Facendola in 2025.
• Arnold Arboretum / Jamaica Plains, MA: Five plants appear on their database of their plant collections. Two were wild collected by Nicholson and Schwartz in 1989 and the three other trees derive from the Biltmore Gardens NC trees. A total of 33 plants from their collection, from Nicholson expedition, were transferred to the Atlanta Botanical Garden in 2010. History of Arnold Arboretum's involvement with conservation of Florida Torreya is available here, and in a 2007 paper by David Ruland.
• Polly Hill Arboretum / Martha's Vineyard / Tisbury, MA: This location is listed by the Center for Plant Conservation as one of the institutions "conserving" Florida Torreya. Polly Hill has 14 Torreyas listed in their collection as of 2017. Located in their conifer row 5 and Holly Park Bed 5 in Hilly's Garden. Plants acquired between 2009 to 2011 — some from Arnold Arboretum in 2010 and some from Torreya Guardians. Their 2011 Year in Review includes this information on page 1:
"Noteworthy among the 2011 accessions are several rare taxa including 8 different clones of the federally endangered Florida torreya (Torreya taxifolia) that were grown from cuttings wild-collected in the 1980s by the Arnold Arboretum. These plants were for many years part of a Center for Plant Conservation (CPC) collection held by the Arnold.Note: Visit our page on Morris Arboretum (Pennsylvania) to learn that: 4 cutting-grown plants were received from the Arnold Arboretum in 2009 and a seedling received from Polly Hill Arboretum in 2015. This is evidence that Polly Hill has at least one Florida torreya producing seeds. 31 July 2020 email reply from Todd Rounsaville to Connie Barlow. Todd informed Connie that April 2020 he shifted from Polly Hill to National Arboretum in Washington, D.C., where he is Lead Scientist Woody Landscape Plant Germplasm Repository. He wrote of the Polly Hill site, "... The Torreyas there were doing okay when I left in April; there were some prostrate forms in the shade that I think came from Jack Alexander. The others (3) were upright, about 4 to 5' tall, and I assume these would have been the ones from you, though if my memory serves Jack Johnston may have been listed as the source." "Polly Hill 2023 Living Collections Inventory" is an online lengthy report which includes the following information on genus Torreya:ABOVE: Because Jack Johnston is listed as the donor of seeds in 2009 and seedlings in 2010 and 2011, the source would be wild genetics from the ex-situ planting in Blairsville, GA. This is thus a very important northern source for (a) producing confirmed wild-genetic seeds and (b) documenting thrival of Florida Torreya in coastal Massachusetts. Note: Polly Hill is mentioned (page 12) as the source for torreyas taken to Mount Holyoke Botanic Garden (South Hadley, MA): "Director Tom Clark brought young plants with him when he moved from curator at Polly Hill to Mount Holyoke. News story states he is growing young plants of Florida Torreya and Florida Yew in the Talcott Greenhouse until they are large enough to plant outside." A 2017 report, "Mount Holyoke College Flower Show", also includes that information:
Mount Holyoke has a Franklinia tree. Because it is only hardy to zone 5 and Massachusetts is at the edge of its range a protected spot will be chosen for planting. Tom Clark explained that by telling the stories behind plants, visitors to the Botanic Garden will better understand their history and their importance. Because of his dedication to the need for conservation and preservation of endangered plants Clark acquired young plants of two of the rarest plants in North America. The Florida yew (Taxus floridiana) only grows in a small area of Florida. The Florida Torreya, (Torreya taxifolia), is also a yew which has been attacked by a Florida fungus. Both are listed as endangered species. Clark will grow his small plants in the greenhouse for some years before thinking about a place for them in the garden. The goal is to see if they can be preserved outside their natural range.
