Tennessee purple-coneflower
Echinacea tennesseensis (Beadle) Small
Description
Tennessee purple-coneflower (Echinacea tennesseensis) is a distinct species of herbaceous perennial within the Asteraceae family. It is widely recognized for its unique, upward-curving ray florets, which distinguish it from the more common varieties of the genus Echinacea.
This plant is endemic to the cedar glades of Tennessee, USA. Its natural habitat consists of rocky limestone outcrops, where the soil is thin and moisture availability varies significantly throughout the seasons. Due to its restricted natural range, the species is protected, though cultivated varieties are available for home gardeners.
Botanically, the plant grows to a height of 20 to 30 inches. Its foliage is lanceolate and typically covered in stiff hairs. The flower heads feature a prominent, dark, reddish-brown cone surrounded by petals that extend upward, giving the plant a refined, goblet-like appearance during the peak summer bloom.
Regarding cultivation, this species demands excellent drainage and full sun exposure. It is highly drought-tolerant, making it an excellent candidate for xeriscaping. The soil should ideally be slightly alkaline and gritty; heavy, clay-based soils that hold moisture throughout the winter months should be avoided to prevent crown rot.
The primary use of Echinacea tennesseensis is in ornamental gardening, particularly in rock gardens or native plant displays. Common pests include aphids and mites, while fungal pathogens may occur if drainage is insufficient.
