Plant Collections Network

Ferns

The University of California Botanical Garden has over 500 accessions of 360 taxa of ferns.  About 65% grow in the outdoor collections, and about 84% are of known wild origin, making them particularly valuable research specimens. In 2012, the Garden’s fern collection was recognized as a collection of national significance by the Plant Collections Network (formerly NAPCC). 

Cycad Multisite

The cycad garden at Ganna Walska Lotusland was one of the last to be added by Madame Walska to her 37-acre estate. Over the years she planted a few individual cycads because they reminded her of her favorite plants, the palms. In the early 1970s, however, she decided to collect as many species of cycads available and displayed them in their own corner of the property.

Hosta

The Toledo Botanical Garden Hosta Collection is accredited by the Plant Collections Network (formerly North American Plant Collections Consortium, NAPCC) and was also designated as a National Display Garden of the American Hosta Society in 2002. 

Mojave Desert Cacti and Succulents

The Plant Collections Network (formerly North American Plant Collections Consortium, NAPCC) of the American Public Gardens Association granted accreditation to the Springs Preserve's Cacti and Succulents of the Mojave Desert Collection. The Plant Collections Network accreditation enables the Springs Preserve to make its cacti and succulent collection available for increased distribution and research, while promoting greater public understanding of conservation issues.

Orchids - Tropical Species

The Smithsonian Gardens Orchid Collection (SGOC) has grown from five plants to over 8,000 specimens since 1974. It is an invaluable resource for educational programs, exhibitions, and scientific research.

This collection is maintained in the Smithsonian Gardens Greenhouse Facility in Suitland, Maryland by staff, interns, and volunteers. It received accreditation from the Plant Collections Network (formerly North American Plant Collections Consortium, NAPCC) in January 2014, making it the first member of the Orchidaceae tropical species curatorial group.

Ilex

The Scott Arboretum holds three Nationally Accredited Plant collections including Ilex (hollies), Quercus (oaks), and Magnolia. Our first collection to get Plant Collections Network (formerly North American Plant Collections Consortium, NAPCC) status was the holly collection.  The lion’s share of this collection is found in the James R. Frorer Holly Collection on the south facing slopes along the Crum Creek. This collection was donated by Swarthmore College graduate, James R. Frorer in 1974 from his property in Wilmington, Delaware.

Mesoamerican Cloud Forest

The San Francisco Botanic Garden was one of the first gardens to commit to holding and developing a collection for the Plant Collections Network (formerly North American Plant Collections Consortium, NAPCC) for their Mesoamerican Cloud Forest. As a holding institution, they protect, propagate and share the listed species. This helps to ensure that no one garden has 'the' only representation of a particular plant species.

Orchid

The Orchid Collection and Cycad Collection of San Diego Zoo Global have been awarded Plant Collections Network (formerly North American Plant Collections Consortium, NAPCC) accreditation. An early leader in the specialized field of zoo horticulture, San Diego Zoo has developed extensive plant collections. Its significant orchid collection includes over 900 taxa with a strong emphasis on the genus Paphiopedilum. Many acquisitions came from the Zoo’s participation as a CITES plant rescue center, receiving orchids confiscated at United States borders.

Griffith Buck Roses

This Buck rose collection is recognized by the Plant Collections Network (formerly North American Plant Collections Consortium, NAPCC) as a national collection. As a member of Plant Collections Network, this collection is preserved with the highest standards, ensuring the Dr. Buck’s work can be enjoyed, and his roses can be used to breed and develop the next generation of landscape roses. There are over 86 named Buck varieties. Reiman Gardens has many of these roses, with more being sought and added each year. Some are presumably missing from cultivation.

Cypripedioideae

The Phipps Conservatory and Botanical Gardens was awarded Plant Collections Network (formerly North American Plant Collections Consortium, NAPCC) accreditation for its Barbara Tisherman Slipper Orchid Collection in 2014. The collection includes 352 species and historically significant hybrids of the Cypripedioideae orchid subfamily.
