Cross vine is a fast growing evergreen (in the south) vine that can grow up to 30 to 50 feet tall. It climbs by using tendrils to wrap around stems or bark to support the vine as it grows up tall objects like fences or pine trees. The tendrils are part of a very unique evergreen leaf system. The leaves are opposite, meaning where this is one on a stem there is another one exactly opposite at the same location on the stem. They are also compound with two leaflets (this is the unique part as most compound leaves have 3 or more leaflets) and one tendril on each petiole (leaf stem). The name comes from the cross pattern seen inside a cross section of the stem (pith). Each leaflet is 3 to 5 inches long and 1 to 2 inches wide. As for color, in our area they are usually a dark, glossy green. However in colder areas of its growing range the leaves may take on a reddish-purple color. This plant is resistant to damage by deer.
This vine is native to the southeastern United States in USDA hardiness zones 6 – 9. It can be found growing native in many soil types, and usually up other trees such as pines. It tolerates a wide variety of conditions, including coastal conditions, but prefers an organically rich, well-drained soil in full sun. Cross vine will grow well in shade to full sun, with better flower production the more sunlight it receives.
The flowers bloom in late winter to early spring on new wood in clusters of 2 to 5 flowers. The flower color can range from orange and yellow to a reddish-orange color. Some cultivated varieties have been selected for the deeper colors such as ‘Tangerine Beauty’. Some of the native vines also have very attractive colors. This early bloom season provides a nice stopping point for hummingbirds in the area.
There are no major pests of Cross vine. However, the vine itself may become a problem. It spreads both by seeds as well as by root suckers. To prevent the vine from spreading to areas where it isn’t wanted, pull up the root suckers as they are spotted.
