Crossvine
by CMG Betty J
Crossvine, Bignonia capreolata, is a hardy vine that grows in both sun and part shade. This woody perennial may grow to 50’ long and displays showy, orange-red or yellow flowers in March, April, and May. The trumpet-shaped blooms are about 2” long and 1 ½” wide and hang in clusters. When growing in the wild, they often climb up a tree and add unexpected color. Crossvines climb via tendrils that have holdfasts, (adhesive pads), at the ends. These holdfasts allow the vine to also cling to stone, bricks, and fences without additional support. The leaves are 4-6” long and are semi-evergreen. They change to reddish-purple in winter.
The name Crossvine refers to the cross-shaped pattern inside the stem. The pattern is the result of the four radial wedges of phloem imbedded within the xylem. Phloem is vascular tissue in plants that conducts sugar and other metabolic substances from the leaves down to the roots. Xylem is vascular tissue that transports water and nutrients from the roots to the stem and leaves.
Crossvine grows in moist, well-drained acidic or calcareous soils, sandy loam, or clay. Water usage is classified as low to medium, although it can tolerate brief flooding. The flowers provide a good nectar source for hummingbirds and butterflies. It is not deer resistant.
