This amazing perennial is unknown in horticultural circles, despite being native from New York to New Mexico. Our collection is from Wake Co., NC. Each plant makes a 2' wide mat of fleshy green foliage, highlighted by erect 1' tall flowering stems. The stems are topped from July through September with rich pure blue flowers (a rarity in the hardy plant world). Although each flower is only open for a day, the succession of blooms rivals most annuals. C. erecta does produce copious amounts of seed, so don't site this where it will seed into other smaller choice plants.
