Colorado desert blue star is an attractive, native, low water perennial flower. It has a pleasing, upright vase-shape form. It is known for being very resilient to Colorado's changing weather conditions.
In April and May, it has light blue, star-shaped flowers in clusters at the tips of the stems. In fall, the leaves turn a bright yellow color.
Unlike some other perennial flowers, Colorado desert blue star maintains a nice appearance throughout the growing season, even when not in flower.
There is one Colorado desert blue star growing at the Xeriscape Garden. It is very attractive and requires little care.
Since it is a small plant, site in an area like a rock garden or the front of a flower bed. It takes several years for the plant to fill in after transplanting. Expect to wait three years until it becomes a mature, full plant.
Cut stems to ground level in late winter before new growth begins in spring.
