True to its name, this native perennial will give you a long-lasting blaze of vibrant purple or pink color beginning in late July and continuing into September. Unlike most flowers, Prairie blazing star also known as Prairie gayfeather and Prairie liatris, features a spike of stalkless flower heads densely packed onto a tall stem which bloom from the top down. The flower spikes, which make excellent cut flowers, cover nearly half of the leafy 2 – 5 ft tall stems and may require some staking in the garden. They are extremely heat and drought tolerant, will stand moist conditions in summer and thrive in full to partial sun and poor soil. Butterflies flock to them.
