Grindelia hirsutula
Grindelia hirsutulaAlso known as Hairy Gumweed, Gumplant, California Gumplant
Hairy gumplants produce bright yellow daisy-like flower heads coated in a thick, sticky white resin before opening. Native to California and western North America, these rugged perennials thrive in sunny chaparral, grasslands, and coastal scrub habitats. Their dense coat of resin deters thirsty herbivores while conserving precious moisture during hot, dry summer months.
