Description
Vitis coignetiae is an ornamental grapevine. It is an extremely fast-growing tendril climber that reaches up to 60 feet (18 m) in several years. It has thick ropy stems and dark green, heart-shaped, slightly toothed, up to 10 inches (25 cm) long leaves.
In the summer, insignificant light green flowers give way to inedible purplish blackberries (grapes) in the fall. Leaves turn crimson red in fall.
Hardiness
USDA hardiness zone 5a to 9b: from −20 °F (−28.9 °C) to 30 °F (−1.1 °C).
How to Grow and Care
Choose a sunny, well-drained position, and at planting time, dig in plenty of organic matter, including a good shovelful of compost. Dig the hole large enough for the roots to spread, and backfill with soil and compost, pressing around the area to get rid of air holes. Water in well and make sure, with a grafted vine, that the graft union is not below the soil – it should be at least 4 inches (10 cm) above the surface.
In early spring, fertilize with a complete fertilizer to establish the new vine, and repeat each year in spring and summer. Grapevines are well adapted to growing in dry conditions, and a drip-irrigation system will deliver water efficiently and adequately. It is a better method than watering overhead, as this can lead to fungal problems, such as mildew on the leaves and rotting fruit. Regular watering is done from September to January and then withdrawn after the fruit is harvested.
