Rudbeckia pallida Nutt. |
Echinacea pallida (Nutt.), the Pale Purple Cone-flower, is a herbaceous perennial plant from a taproot in the family Asteraceae. Plants are similar to Echinacea angustifolia, but often growing taller, ranging from 1.5 to 2.5 feet (45 to 75 cm) tall but sometimes 3 feet (90 cm) or more high. Plants normally grow with one unbranched stem in the wild but often growing into multi-stemmed clumps when grown in gardens. The deep taproot is spindle shaped, wider in the center and narrowing at the ends. Stems are green in color or mottled with purple and green. The leaves are elongated lanceolate or linear-lanceolate in shape with three veins, and the margins are entire. Flower head rays narrow, linear, elongated, drooping, from 1 to 3 inches (2.5 to 7.6 cm) long. The flower heads are from 0.75 to 3 inches (2 to 7.6 cm) wide with pale rose-purple or nearly white colored petals, the flowers have white pollen. The fruits are called cypselae and are tan or bi-colored, with angled edges.
Native from dry soils in prairies in the USA, from the states of Illinois to Michigan, Alabama and Texas. Echinacea pallida is found blooming from May into July. The states of Tennessee and Wisconsin list this species as threatened, mostly do to habitat loss and over collection of roots. The roots are collected to be made into herbal medicine but the use of Echinacea as a medical plant has not been demonstrated to have any positive health effects.[1][2][3][4][5][6]
