HORTICULTURAL
Plant Sale Text: The late-blooming southern blazing-star shares its purple color and spiky habit with other members of its genus. Those familiar with the others will notice, however, that instead of a continuous spike of purple, the larger flower heads of this Liatris are separated by an inch or more of stalk. Southern blazing-star has a range that includes the southeastern United States and extends west to Texas and north to Ohio. It is present though not common in North Carolina. This plant makes its home in open woodlands on dry rocky or sandy soil. It is well adapted to dry conditions and is drought-tolerant once established. 1998 Wildflower of the Year.
