Rare Plant Sponsorships at the Arboretum

Give as a gift or sponsor one yourself Dudleya formosa

  • Sponsor a plant for $50
  • Sponsor a staff member taking care of rare plants $100
  • Co-sponsor a species for $500
  • Sponsor a species for $1000

Help us save a rare species locally or from the far corners of the earth: California, South Africa, New Caledonia and conifers, Australia and New Zealand.

You may sponsor multiple plants in the same species or multiple species. People may give one-year sponsorships as birthday or holiday gifts.

Gifts will support educational efforts and keeping the plants alive in cultivation. With your help, we will work towards long-term strategies to save these plants in the wild, too.

What you get:

  • $50 - We email you a certificate commemorating your donation. You get to enjoy the feeling of knowing you are helping these lovely plants survive.
  • $100 and up - We mail you a certificate. You get to enjoy the feeling of knowing you are helping these lovely plants survive. Each species supports animal life in one way or another too, so preserving the plants helps the ecosystems, not just the species.
  • $500 and up – Choose if you want staff to show you your species at the Arboretum or a brief written update on the species. We mail you a certificate of sponsorship.
  • $1000 and up - Choose if you want staff to show you your species at the Arboretum or a brief written update on the species. We mail you a certificate of sponsorship. Plants of the rare species already in the garden are eligible to have a tribute plaque by the plant.

How to do it:

Simply print the sponsorship form and mail it with your donation to:

Available Rare Plant Sponsorships:

California

Planting Little Sur Manzanitas at Pt. Sur Arctostaphylos edmundsii – Little Sur Manzanita
The Arboretum has been growing this for years. Lately, we have been replanting them in an area by the Point Sur Lighthouse after removing invasive plants. We will continue to work with State Parks to replant them in the wild.
Ohlone Manzanita Arctostaphylos ohloneana – Ohlone Manzanita
Only known from about 150 plants in Santa Cruz County. They were named in 2009 by Mike Vasey, a member of the Arboretum's Science Council and by Tom Parker. They were discovered by the Arboretum's Visiting Regent’s Scholar, R. Morgan. We will propagate and distribute plants to other gardens.
Verity's liveforever Dudleya verityi – Verity’s liveforever
Read how the entire habitat of the already-threatened Verity's liveforever was burned in a recent fire and how seeds from the UCSC Arboretum may help save it from extinction in this UCSC press release.
Malibu liveforever Dudleya cymosa subsp. ovatifolia – Malibu liveforever
Severely threatened by rock climbers. It only grows in two canyons. Plants from Orange County are not the same species, so this turns out to be even more rare than when it was listed as endangered.
Dudleya linearis Dudleya linearis
We received a small cutting of D. linearis in 1986 when the species was doing fairly well. By the late 1990s there were few or none in the wild. After rabbits were removed, the plants started to sprout from seed that had remained in the soil. It is not known if there are still pollinators to transfer pollen. Our single plant produces almost no viable seed, unless crossed with different plants, so cross pollination may be important or imperative in the wild.
Dudleya formosa Dudleya formosa
Dudleya formosa is an extremely rare succulent from Baja California threatened by roadwork, garbage dumping, urbanization, and collecting. It only grows on one cliff in the wild. We would like to start selling some of our very pink flowered plants in 2015, if we can significantly increase the number of plants we have in the collection. The typical ones are good back-ups for the rare plants in the wild.
Unnamed Baja liveforever An unnamed species of liveforever from Baja California.
Threatened by development and agriculture.
Silicon Valley Dudleya Silicon Valley Liveforever
Very few plants, not named. Very different from the Santa Clara Valley liveforever. Threatened by urbanization, road maintenance.

South Africa

Leucospermum grandiflorum Leucospermum grandiflorum
Rare in the wild. Some in cultivation, but many are hybrids.
Gasteria Gasteria species
Many are very rare, but fortunately many of the rare species are being cultivated fairly widely.

New Caledonia and Conifers

Aruacaria Araucaria humboltensis
No longer reproducing in the wild. No longer reproducing viable seed in the wild. IUCN says, “a very high risk of extinction.” Risks include fire and disease (and mining?)
We will continue to grow it, and collect seed when it matures.
Aruacaria luxurians Araucaria luxurians
Rare. Populations declining. IUCN says, “a very high risk of extinction”. “No more than 2500 mature individuals.” Some pressure from collectors? We will grow and propagate this species.

Australia

Banksia brownii foliage Banksia brownii – feather leaved Banksia
Critically endangered. Ten of the thirty populations are now extinct due to disease. Another 80% are expected to die. We will continue to grow these as an out of country back-up.
Banksia solandri Banksia solandri.
Endangered by fire and disease. All wild populations infected by Phytophthera fungus. Needs to be 8-10 years old to set seed and some don’t get that old before disease or fire intervene. Endemic to the Stirling ranges in West Australia. Frost sensitive at 24°F, so limited in where it can be grown off-site. We will propagate from seed. Six plants at the Arboretum in March 2013.

New Zealand

Melicytus obovatus Melicytus obovatus and/or rare, related subspecies
A large flightless parrot called a Kakapo feeds on the berries of this or a related species. There appears to be some relationship between the smell of the berries and the smell of the rare bird that may or may not relate to the bird’s survival. We will continue to grow and provide samples for the researcher looking into the relationship between this bird and plant. The population of the parrots was down to 14-19 females in 1992 and is only slowly recovering. The Arboretum does have the Rimu tree, a species clearly important to feeding the birds in the wild. The parrots breed after a very good year for the Rimu trees.
