Outstanding Qualities

In early summer, Dichelostemma congestum has a compact ball of long lasting lilac-purple flowers two-to-three inches across on a 24 inch stem with two or three grassy leaves at the base. Its flower looks similar to the head of an Allium. Dichelostemma congestums are native to the west coast and grow naturally in open, grassy areas. It works well as a cut flower, but watch the sap as it can be irritating to some. Since it is a native it is very drought tolerant and actually prefers no summer water. Ookow looks ideal in combination with sun loving grasses and other bulbs.

Culture Notes
This unusual bulb does best in well drained soil with full sun, but will tolerate clay. It resents summer watering and is very drought tolerant. The foliage will grow in late winter and spring then begin to die back as the flower stems form. Once flowering has finished the faded flowers and stems can be cut to the ground. This bulb is best planted in fall.
Geek Notes
This native bulb is found in British Columbia, Canada, parts of western Washington, much of western Oregon, and northwestern California.
