Foliage: The leaves are dark green, semi-evergreen to evergreen, and typically retain their color year-round in warmer climates. In colder regions, they may drop in winter.

Flowers: Produces trumpet-shaped, deep red to burgundy flowers with a yellow throat, typically blooming in spring and occasionally re-blooming in fall. The flowers are highly attractive to hummingbirds and other pollinators.

Deciduous/Evergreen: Bignonia capreolata var. atrosanguinea is semi-evergreen to evergreen, depending on the climate. In warmer regions, it typically retains its foliage year-round, while in colder areas, it may lose some or all of its leaves in winter.

Light Requirements: Prefers full sun to partial shade. Crossvine thrives best in full sunlight, which promotes vigorous growth and abundant flowering. However, it can tolerate partial shade, especially in hotter climates, where some protection from the intense afternoon sun can prevent leaf scorch and maintain vibrant blooms.

Soil Requirements: Prefers well-draining, fertile soil. This plant grows well in a variety of soil types, including sandy, loamy, and clay soils, as long as they are well-draining. The ideal soil pH range is slightly acidic to neutral (6.0-7.5). Incorporating organic matter, such as compost, can enhance soil fertility and improve drainage, supporting healthy growth.

Watering: Requires moderate watering, especially during the first few years after planting. Crossvine prefers consistently moist soil but is moderately drought-tolerant once established. Water deeply and regularly during the growing season to keep the soil moist but not waterlogged. Overwatering should be avoided to prevent root rot.

Temperature and Humidity: Hardy in USDA zones 6-9. Crossvine is well-suited to a range of climates, from temperate to subtropical regions. It can tolerate occasional frost and cold winters but performs best in warm, humid environments. In colder zones, it may benefit from some winter protection, such as mulching around the base of the plant.

Fertilization: Apply a balanced, slow-release fertilizer in early spring to encourage healthy growth and vibrant flowering. An additional application in mid-summer can help sustain the plant during its peak blooming period. Organic fertilizers, such as compost or well-rotted manure, are also beneficial for maintaining soil fertility.

Pruning: Prune after flowering to control growth and shape the plant. Crossvine can grow rapidly, so regular pruning is necessary to keep it in check, especially if grown on a trellis, fence, or wall. Remove any dead or damaged branches to promote healthy growth. Light pruning can also help maintain a more compact and bushy appearance.

Pests and Problems: Generally pest-resistant, but may occasionally be affected by aphids, scale insects, or fungal diseases. Ensuring good air circulation around the plant and avoiding overhead watering can help prevent fungal issues. If pests or diseases are detected, treat with appropriate measures such as insecticidal soap or fungicides.
