Crossvine
Bignonia capreolata (big-NO-nee-uh kap-ree-oh-LAH-tah)
Cross-vine is a vigorous, perennial vine in the trumpetvine family (Bignoniaceae). This vine is native to the southeastern and south-central United States. A cross-section of its stem reveals the conducting wood forming a cross, hence the common name. The species epithet means “having tendrils.” Cross-vine tolerates a wide variety of conditions, including coastal conditions, but prefers organically rich, well-drained soil. It will grow well in shade to full sun, with better flower production the more sunlight it receives. In North Carolina, the vine is usually a dark, glossy green; however, in colder areas of its growing range, the leaves take on a reddish-purple color. In severe winters, the vine may die to the ground, but the roots are usually hardy enough to survive and will sprout new growth the following spring. Cross-vine may be propagated by root cutting or seed. In the wild, it is found climbing trees in swampy forests and woodlands. The vine blooms in late winter to early spring on new wood in clusters of two to five flowers. Its early bloom season provides a critical food for hummingbirds in the area. This vine would make a great addition to a colonial-style garden, native plant or pollinator garden. It is also suitable for a children’s garden. Several cultivars with improved color, such as 'Tangerine Beauty', are available. Fire Risk: This plant has a high flammability rating and should not be planted within the defensible space of your home. Select plants with a low flammability rating for the sites nearest your home. Insects, Diseases, and Other Plant Problems: There are no major pests of Cross-vine; however, the vine itself may become a problem. It spreads both by seed as well as by root suckers. To prevent the vine from spreading to areas where it is not wanted, pull up the root suckers as they are spotted.
