Family: Vitaceae
What it is like
Vitis romanetii is a deciduous Climber growing to 10 m (32ft 10in). See above for USDA hardiness. It is hardy to UK zone 6 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 cannot grow in the shade. It prefers dry or moist soil.

How it is grown
Prefers a deep rich moist well-drained moderately fertile loam. Grows best in a calcareous soil. Requires a position in full sun. This species is not hardy in the colder areas of the country. Young growths and thin wood can be cut back by frosts. Plants climb by means of tendrils. Closely related to V. davidii. Plants are rather tender in Britain when they are young, though older plants are hardy in most parts of the country. Any pruning should be carried out in winter when the plants are dormant otherwise they bleed profusely. 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. Layering.
