Dotted blazing star is a native plant that grows naturally on the Great Plains. It is an upright plant with one to several stems that arise from a central crown.
In late summer, dense purple flower spikes adorn the plant. The flower clusters bloom over a period of time, starting at the top and progressing downward.
Dotted blazing star gets its name from the light-colored glandular dots that occur on the narrow, dark green leaves. Because it's adapted to the central prairies, it can grow well in landscapes with dry, sandy soils. It can also blend well with native grasses in a prairie-style landscape.
At the Xeriscape Demonstration Garden, this species is located in a very dry location. The flowers are very attractive and draw attention with their unusual color and shape. They reseed themselves, but not enough to be noted as a nuisance.
Remove spikes of spent flowers after bloom.
