Castilleja minor var. exilis
Annual Paintbrush is a delicate wildflower native to North America. This unique plant has large, spoon-shaped yellow bracts of flowers that rise above threads of foliage typically reaching heights of 6-12 in. This hardy and easy to grow species is often found on gravelly soils and dry grasslands in full sun. It's a great addition to any rock garden or wildflower meadow, with its showy flowers blooming in late spring that last until early summer. Annual Paintbrush is an evergreen in mild climates, and a great source of nectar for bees and butterflies.
