This species is a woody perennial vine commonly known as Grape, the fruits grow in clusters of 15 to 300, and can be crimson, black, dark blue, yellow, green, orange, and pink. Flowers and subsequent fruit develop on new shoots called canes. Annual pruning is very important to keep this type of growth healthy and rejuvenating each year. Grapevines usually only produce fruit on shoots that came from buds that were developed during the previous growing season. Flower buds are formed late in the growing season and overwinter for blooming in spring of the next year. The fruit is a berry, ovoid in shape and juicy. Other parts of the vine include the tendrils which are leaf-opposed, and are used to support the climbing plant by twining onto surrounding structures such as branches or the trellising of a vine-training system.
