Clematis texensis Buckley
Scarlet Clematis, Scarlet Leatherflower, Texas Clematis
Ranunculaceae (Buttercup Family)
Synonym(s): Clematis coccinea, Coriflora texensis
USDA Symbol: CLTE2
USDA Native Status: L48 (N)
Scarlet leather-flower or scarlet clematis is an herbaceous to slightly woody vine, climbing to 9 ft. Bell-shaped flowers, blooming only on new growth, are held in axillary clusters of one to seven. The flower petals are actually thick, leather-like, scarlet-colored sepals. A feathery ball of plumed seeds follows the floral display. Stems are bare for the first two feet.
This is a very hardy and drought tolerant clematis. Under ideal, sunny conditions, blooms may last until the first frost. Widely cultivated because of the red flowers but native only to the southeastern Edwards Plateau in Texas.
