Snapshot: Fremontia is a fast-growing evergreen shrub with fuzzy leaves, inspiring its nickname, flannel bush. (Warning: The fuzz on its leaves is easily brushed off upon contact and can be a skin and eye irritant.)
Native to the Southwest and Mexico, this shrub is drought-tolerant with a shallow root system.
From spring to summer, fremontia explodes with bright, showy and intense yellow flowers that attracts bees and butterflies. Landscape companion plants that would add to the show-stopper effect include purple-flowered salvia, blue-blossomed ceanothus and manzanita, which has light pink flowers.
Fremontia grows in an unruly shape — so if space is not an issue, allow this plant to do its own thing and your reward will be a massive amount of gorgeous bright yellow flowers.
If space is limited, prune fremontia in late summer or early fall, which will allow for fast healing of pruned surfaces. Be careful to only prune crowded sections, damaged branches or diseased growth. Once established, Fremontia has a low-water requirement, a very attractive trait for a drought-tolerant landscape.
