The top two-thirds of prairie blazing star is a spike of rose-purple, thistle-like flowers that are given a somewhat fuzzy appearance by extended white stamens (male flower parts) and pistils (female flower parts). Flowering starts at the top of the spike and moves progressively downward. Each flower head along the spike is made up of 5 to 12 tubular florets.
The flowers at the top of Prairie blazing star spikes are the first to bloom. Blooming will slowly progress down the spike. Flowers typically bloom in late summer and early fall. These are a great species to report on during the Fall into Phenology campaign!
