Cross-vine is a vigorous woody vine from the Bignoniaceae family that climbs by branched tendrils equipped with adhesive disks, making it exceptional at rapidly covering structures with attractive foliage. Hardy in zones 5 through 9, it produces fragrant, showy flowers in May and June that reward its effort with color and scent. The vine grows tall, reaching 20 to 30 feet vertically with a spread of 6 to 9 feet, and thrives in full sun to partial shade, though it tolerates even heavy shade. What truly sets this variety apart is its combination of vigorous growth habit, ornamental foliage, and reliable performance across a wide hardiness range.

This vine climbs with remarkable speed using branched tendrils that grip surfaces with adhesive disks, so it needs minimal support once established. The opposite, compound leaves consist of pairs of dark green leaflets reaching 6 inches long, creating dense, attractive coverage that remains on the plant through the growing season. Flowers appear in May and June with both fragrance and visual impact. In colder parts of zone 5, stems may die back during severe winters, but the roots persist and sprout fresh growth come spring, so this vine rewards patience and protection.
Cross-vine is grown primarily as an ornamental climber for covering walls, fences, arbors, and other structures. Its combination of rapid growth, attractive foliage, and fragrant flowers makes it valuable for landscaping applications where quick coverage and visual interest are desired.

Prune after flowering in June if you need to shape the vine or control its spread. The vigorous growth habit means regular pruning will help maintain the desired form and encourage bushier development if desired.
