Liatris microcephala
Dwarf blazing star
An exceptional compact native with fine-textured, deep green, grassy leaves, Dwarf Blazingstar sends up numerous spikes with tassel-like rosy purple flowers in August and September. Unique to the genus the flowers open from top to bottom on the spike in a slow unfurling of brilliant color. Excellent as a cut flower. Tolerant of clay and drought, very low maintenance. Loved by butterflies! Liatris microcephala (microcephalus) can be found in sandy, dry prairies and open glades of the Southern Appalachian Mountains.

Interesting Notes
Proven hardy greenroof plants are the Alpine types and those that can retain a certain amount of moisture within their leaves or bulbs. So, in theory, other plants known to flourish in areas of high heat, drought, wind, direct sun, and temperature extremes should be particularly adaptable to the sometimes harsh conditions of a greenroof. I would speculate that most plants naturally occurring along county roads, expressways, abandoned sites and the like that do not receive irrigation would adapt well to the greenroof environment.
