Great Valley Gumweed, Resinweed, Boton de Oro
Providing color through the summer and autumn months, Grindelia camporum (Great Valley Gumweed) is a perennial, semi-woody subshrub with erect, branching, white-varnished stems lined with alternate, lance-shaped leaves. The leaves are stalkless, often with clasping bases, up to 2.5 in. long (6 cm), and dotted with glands that produce a sticky resin. Blooming in profusion from late spring to late fall, yellow daisy-like flower heads, 2 in. across (5 cm), appear above the foliage. Each daisy is composed of 25–39 yellow ray flowers surrounding a yellow center disk. They sit above a whorled cup of sticky-glandular, green bracts, with long, spreading, thin tips. Immature flower heads are spheroid and ooze sticky, white latex that gives them a milky appearance. The flowers are an important late-season source of pollen and nectar for bees, honey bees, syrphid flies, and butterflies. They give way to small, dandelion-like achenes with featherlike tufts. The seeds are a food source for many songbirds. Great Valley Gumweed dies back in the winter to a basal rosette of leaves before returning again from the perennial rootstock. Native to California and Baja California, Great Valley Gumweed may be found in sandy or saline bottomlands, dry banks, rocky fields, plains, and roadsides. Highly drought and salt tolerant, this plant persists throughout the late summer months when other plants wither. It is an attractive perennial for use in wildflower meadows, butterfly gardens, and gardens close to the coast. It can also be used in prairie and wetland restoration projects, pollinator enhancement plantings, and hedgerows. Historically, Great Valley Gumweed has been used in herbal remedies to treat respiratory maladies, dermatological conditions, blood disorders, and minor injuries.
