Clematis texensis Buckl.
Native only to seven counties on the Edwards Plateau in Texas, this is the only true red flowered species. Flowers are ovoid to urn-shaped and rose-red to scarlet. In its native range, the vine is found on moist, humusy soils; in woodlands, and on stream banks and calcareous cliffs. The foliage is glaucous, and looks similar to C. versicolor. In a garden setting in Pennsylvania, a mature vine begins flowering in June and continues through September. It grows about 10 feet (3 meters) tall. Hummingbirds are attracted to the flowers, and the seed heads are highly ornamental. Although texensis has been used extensively in hybridizing, the hybrids should not be given the species epithet "texensis", since they usually have only 50% texensis genetics at best. Unfortunately somewhat susceptible to mildew, especially in late summer. Hardy in zones 5-9. Images:Some pictures © Miguel E.
