Crossvine (Bignonia capreolata)
Click on terms for botanical definitions.
Crossvine is a perennial evergreen vine, so named because a cross-section of its stem reveals a cross-shaped pattern. It typically blooms in spring, when it puts on a spectacular display, but they can appear as early as February and as late as June. It occurs naturally in mesic to dry hammocks, floodplain forests and dry hardwood forests. It is mainly pollinated by hummingbirds but attracts some butterflies, as well.
The flowers are long (2–3”), tubular and reddish-orange with yellowish throats. They are borne in showy clusters that emerge from the leaf axil. Both corollas and calyces are five-lobed. Its compound leaves are dark green, petiloate and oppositely arranged. Each leaf bears two lanceolate leaflets and a tendril. The stem is robust, growing to about 1” in diameter. The fruit is a long brown bean-like capsule that splits when dry to expose its winged seeds.
