San Francisco Gumplant
(Grindelia hirsutula var. maritima)
Origin Of Genus Name: Grindelia is named after D.H. Grindel, 1776-1836, Latvian botanist.
Presidio Locations: Coastal bluffs and coastal hillsides usually on serpentine soils.
Range In State: Coastal areas of central California. The Presidio is the type locality for this species.
Description: This rare native perennial species grows one to two feet tall with herbaceous stems originating at a woody base. The Gumplant is somewhat resinous, particularly the flower head. The fairly thick leaves have fine saw-toothed edges. The flower is daisy-like and yellow, and the buds are topped by a drop of gummy material. Blooms August to September.
Native Californian Uses: An infusion of pulverized leaves were applied to sores by the Miwok. Also used by the Pomo as a sedative, antispasmodic, expectorant, to treat poison-ivy, and as a tea substitute.
Did You Know?
Over 60 species of bees can be found in the Presidio. This very diverse population results from ample nesting habitats in the Presidio’s soft, sandy soils, as well as a large variety of coastal scrub plants to provide nectar and pollen.
