The profusion of small, creamy white, fuzzy flowers, tinged with pink or red are highly attractive to butterflies, bees and other beneficial insects. Extremely tough and easy to grow in full sun with summer water, where it will grow 6 - 10 feet tall and wide with rich, green foliage. Able to survive drier conditions than a willow could handle, but it will look rough if it gets too dry. Responds well to pruning and can be cut down to six inches to refresh. Excellent screen, windbreak and for soil stabilization. Stellar for attracting pollinators.
Brodiaea elegans
From grassy meadows and open woodlands comes this drought tolerant and colorful wildflower. Open clusters of dainty violet flowers sit atop stems reaching 8 to 20 inches in height. Plant in full sun to bright shade and provide decent drainage. As the name suggests, the harvest Brodiaea is the latest blooming of the Brodiaeas, sometimes not flowering until the end of summer after the grass-like leaves have gone dormant. It spreads rapidly but not invasively to form broad drifts. After blooming, this bulb will sleep until the return of winter rains. Do not irrigate. An excellent candidate for the rock garden where its graceful form will contrast wonderfully with the rigid stone.
Calochortus luteus
This showy mariposa lily offers vibrant, golden-yellow flowers, often with reddish brown markings at the base of each of the three petals. The upward facing, bowl-shaped flowers seem to hover over grasslands on stems reaching one to two feet tall. In early winter, grass like leaves emerge from the soil, followed by the butterfly-favored blossoms in late spring and early summer. Once the flowers are done, this native bulb will go dormant. Plant in full sun to light shade with well-draining soil. Allow to go completely dry in the summer. Said to be one of the easiest of the mariposa lilies to grow in gardens.
