OOKOW. The common name for this wonderful native bulb. A naked lily closely related to Brodiaea. Also, referred to as cluster lily though that isn’t even remotely as fun to say as OOKOW. Stems to 22″ tall support 6 to 15 showy purple flowers clustered at the stem tip. Dry sunny hillsides in clay soils to meadows throughout western Oregon. Its native range goes a bit to the north into Washington and south to California but its primary populations are in our state. This happy bulb spreads to form colonies in time. It will also spread by seed. An integral part of Willamette Valley meadows. Excellent cut flower that lasts a week in a vase. Water to establish when planting from containers. In subsequent years it will rely only on what falls from the sky. in habitat it can be found with native clumping grasses such as Koeleria and Festuca roemeri var. roemeri. Sisyrinchium idahoense is a frequent associate. The flowers nod slightly at the end of the stems. Smalll grassy foliage appears in early spring and disappears cleanly following bloom. Adapted to heavy clay soils that are wet for 6 months of the year that dries in summer. Full sun. Loved by Hummingbirds and butterflies. Oregon native plant.
This bulb is native from southern Lane County in west central Oregon south into California. Its an easy to grow showy bulb that performs very well in gardens. It should be grown more often. I first saw this plant in the wild near Elkton, Oregon. I was driving by not very slowly and I saw a flash of red in front of a fence. i went back to investigate and found this plant in full bloom. In its habitat it occupies dry sunny slopes that face south. Soil is loam to clay but all of them dry completely in summer. Blooms mid- to late spring for an extended length of time for a bulb. A handful of scrappy leaves forms a rosette . And the blooms extend to about 18″ tall. They are not always straight and can wind, vinelike around and through other plants. The red buds reflex when open to reveal a yellow interior. I’ve had many hummingbirds visit mine. Let it go completely dry in summer- in fact it excels in wild environments and competes very well with weeds. Leaves disappear quickly after bloom. Increases over time. Deer resistant.
