The "difficult horticultural problem," he points out, is that "the host specificity has a genetic basis and thus matching the host to the seed source would be important, as well as the soil type." He grew C. affinis "probably grows with many different hosts," he said via e-mail. When Fred Hrusa, a senior taxonomist with the California Department of Food and Agriculture, grew castilleja 30 years ago for a revegetation project, he gained insight into this genus. Castilleja latifolia grows in the dunes there and is quite spectacular, Wetherwax says. In the effort to re-establish native plants like paintbrush, they have removed ice plants in favor of natives. While you're down in the Monterey area looking for paintbrush later in the year, check out what the California Native Plant Society has done along those beaches. "Some of the best can be seen at Pescadero Marsh along Highway 1." Summer is the best time for viewing them. Wetherwax points out that Indian paintbrushes grow up and down the coast. It is found at elevations from sea level and up to and 984 feet. It belongs to the coastal scrub community of plants. It survives in the extreme conditions generated by its closeness to the ocean, strong sun, dense fog, salt spray and the shallow soils of the rock face. Scruffy colonies of bright orange-red paintbrushes jut up from the gray rock. It can be found growing on bluffs overlooking the Pacific Ocean at Point Lobos State Reserve, just south of Carmel. Castilleja wightii, named to honor 19th century Scottish surgeon and botanist Robert Wight, is a California native plant found only in our state. Pests/diseases: Since it seldom grows in gardens, no known diseases or pests are listed.Ĭomments: The name castilleja honors 18th century Spanish botanist Domingo Castillejo. Give it good drainage, with rocky soil and sand. So where can you grow this plant in your garden? Because it thrives on rocky bluffs or in dunes, an open garden spot with light and air is ideal. The best to try for Castilleja wightii would be its associates in the beach and dune community, such as Eriophyllum stachaedifolium (Lizard tail), Eriogonum parvifolium (Seacliff buckwheat), Erigeron glaucus (Seaside daisy)." Soil conditions have to match, which means growing paintbrushes can be difficult. Margriet Wetherwax, managing editor of the Jepson Flora Project in Berkeley, names these hosts for annual and perennial paintbrush forms: "The annuals can be grown in pots with annual grasses, such as Aira, but the perennials are more host specific. (510) 549-0211.Ĭultivation: Paintbrush can be grown in California gardens with the right host.

In some years, when bluebonnets (which flower at approximately the same time as Indian paintbrush) are especially colorful, paintbrush will have only an average flowering year. Indian paintbrush has a reputation for being unpredictable. The roots of this plant will grow until they touch the roots of other plants, frequently grasses, penetrating these "host" roots to obtain a portion of their nutrients. Together, the flowers and bracts form 3-8 in. They sometimes produce a light yellow or pure white variation mixed in with the reds. The flowers are actually inconspicuous and greenish, but are subtended by showy, red-tipped bracts. Its several unbranched stems form clumps topped by bright-red, paintbrush-like spikes. One of the popular paintbrushes, this showy annual or biennial grows 6-16 in.
