Description

Scarlet clematis is a small vine that flowers on new growth (Pruning Group 3), so it should be pruned in late spring. It will need regular fertilizing throughout the growing season to support lush growth.   It is drought tolerant and has a better density than most clematis. This plant has grayish-green leaves and has wonderful scarlet, bell-shaped flowers from summer to frost. It is native to Texas, where it can be found on limestone cliffs, rocky slopes and along stream beds.

It should be planted in sun but give shade to the roots by overplanting with other perennials or cover roots with mulch or rocks. It can be trained to climb up a fence, arbor or trellis or it can cover over rock walls.  It is a great choice for small spaces.

Insects, Diseases, and Other Plant Problems: No serious problems.  Powdery mildew, stem rot, and wilt may occur.
