Threeleaf Lewisia
Lewisia triphylla
About Threeleaf Lewisia (Lewisia triphylla) 0 Nurseries Carry This Plant Lewisia triphylla is a species of flowering plant in the purslane family known by the common name threeleaf lewisia. It is native to western North America from British Columbia to California to Colorado, where it grows in mountain and forest habitat, often in wet, rocky alpine areas where it may bloom through the snowmelt. This is a perennial herb growing from a fibrous taproot and corm unit. Instead of a basal rosette like many other Lewisia species it produces 2 to 5 short, slender, fleshy leaves from the lower part of the stem, which may be at or under the soil surface. The small stem bears an flower cluster of 1 to 25 flowers. The flower has 5 to 9 small white or pinkish petals often marked with darker veining or stripes.
