California Natives, the entrance garden
The California Garden, on the right as you enter the Arboretum, boasts many special plants of interest to gardeners. Many of these were originally selected in the wild by Arboretum staff, and have since been propagated and released to the horticultural trade.
Many varied native blooms are currently well represented in the California Garden. Highlights this summer include the bright yellow blooms of the Dendromecon harfordii (Channel Island Tree Poppy) and the Encelia californica (California Brittlebush). Other natives include the Eriogonum fasciculatum var. foliolosum Leafy California Buckwheat, that blooms in summer and attracts bees and butterflies, and the Epilobium canum (California Fuschia), which is now displaying its showy trumpet shaped blooms that are loved by hummingbirds.
