Scarlet Clematis – A Texas native through and through, Scarlet Clematis is a slender, herbaceous vine prized for the nodding, urn-shaped flowers in glowing scarlet it carries through the warm months. Found in the wild only in central Texas, it is exactly the kind of well-adapted regional plant the garden grows, trials, and shares. Give it sun to light shade and well-drained soil, and let it scramble through a low shrub or up a trellis. Offering it through the nursery is one way the garden’s conservation work reaches gardeners across the region.
