Faits intéressants

Riverbank Grape is a vigorous vine with woody, twining stems and large, heart-shaped leaves. Small greenish flowers appear in late spring, followed by clusters of dark purple to blue-black grapes that ripen in late summer or early fall. It can spread extensively and may smother smaller shrubs and plants if left unmanaged. It is best suited to large naturalized gardens, fences, arbors, trellises, woodland edges, and property boundaries. Provide a strong support structure; mature vines can become very heavy. Regular pruning in the dormant season is important in a residential garden. It will produce more fruit with good light. It can tolerate moist soils and occasional flooding. Once established, it is relatively drought tolerant. It is not recommended for a small garden unless the gardener is prepared to manage a vigorous vine.
