This group of around 60 species of bulbs is found in the Americas, especially the western regions of the U.S.A. Variously known as mariposa tulip, sego lily, or fairy lantern, most species form a clump of narrow grassy leaves, and in spring and summer wiry stems carry flowers with 3 petals and 3 petallike sepals. The flowers, which cover a wide color range and are often beautifully marked, may be upright or nodding, and when upward facing they can be rather tulip-like. The genus name Calochortus comes from the Greek kallos (beautiful) and chortos (grass). In the past, Native Americans are the bulbs of certain species. Calochortus nuttallii is the state flower of Utah.
CULTIVATION
Although mainy very hardy, mariposa tulips require a climate that is warm and dry in summer. Plant in full sun in gritty free-draining soil-a rockery or raised bed is ideal. Water well from late winter on but allow them to dry off after flowering. Propagate by division in autumn or raise from seed.
Top Tip
Calochortus species are thought to be difficult to grow, but given plenty of summer sun, a good location, and enough water when growing, they will reward gardeners with lovely blooms.
