Crimson Glory Vine
Vitis coignetiae

Family: Vitaceae

What it is like

Vitis coignetiae is a deciduous Climber growing to 20 m (65ft) by 20 m (65ft) at a fast rate. See above for USDA hardiness. It is hardy to UK zone 5 and is not frost tender. It is in flower from June to July, and the seeds ripen from September to October. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil.

How it is used

Food

Rating: 2

Fruit - raw or dried for winter use. The fruit is about 12mm in diameter and is carried in bunches, but it is scarcely edible. Young leaves are wrapped around other foods and then baked, they impart a pleasant flavour. Young tendrils - raw or cooked. Young stems and leafstalks - boiled.

Stem: this often intergrades into leaves.

A yellow dye is obtained from the fresh or dried leaves. Plants can be used as a ground cover in a sunny position. They are best spaced about 3.5 metres apart each way. They can be encouraged to cover the ground by laying brushwood flat on the ground and pegged into position. The twigs would eventually rot and the plant would assume complete and constant control.

Dye: Plants that provide dyes.

Ground cover: Ground Cover

How it is grown

Prefers a deep rich moist well-drained moderately fertile loam. Grows best in a calcareous soil. Succeeds in sun or partial shade though a warm sunny position is required for the fruit to ripen. The fully dormant plant is hardy to about -25°c, though the young growth in spring can be damaged by late frosts. Plants climb by means of tendrils. Any pruning should be carried out in winter when the plants are dormant otherwise they bleed profusely. A fast growing climber, attaching itself by means of tendrils, it is ideal for growing into large trees. Plants are often slow to establish, taking 1 - 2 years from planting out before they make much new growth. A very ornamental plant with its large leaves which colour well in the autumn. Plants in this genus are notably susceptible to honey fungus.

Propagating it: Seed - best sown in a cold frame as soon as it is ripe. Six weeks cold stratification improves the germination rate, and so stored seed is best sown in a cold frame as soon as it is obtained. Germination should take place in the first spring, but sometimes takes another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter. Plant out in early summer. Cuttings of mature wood of the current seasons growth, December/January in a frame. These cuttings can be of wood 15 - 30cm long or they can be of short sections of the stem about 5cm long with just one bud at the top of the section. In this case a thin, narrow strip of the bark about 3cm long is removed from the bottom half of the side of the stem. This will encourage callusing and the formation of roots. Due to the size of these cuttings they need to be kept in a more protected environment than the longer cuttings. Cuttings are difficult from this species. Layering. This is the best method for this species.
