Thinleaved owl's-clover
Orthocarpus tenuifolius
Thinleaved owl's-clover is a delicate Pacific Northwest wildflower that grows best in open meadows and grassy slopes with partial shade and consistent moisture. It is a hemiparasitic plant that depends on nearby host grasses for nutrients, making it challenging to establish outside its native habitat. It is best appreciated as a native garden accent or restoration plant in its natural range across the northern Rockies and Pacific Northwest.
