How to identify Frost grape (Vitis vulpina)

Frost grape, also known as Wild grape

Frost grape is a vigorous woody deciduous vine with a notable capacity for longevity. This species displays an ability to climb and spread considerably when supported, creating a dense and sprawling habit. The leaves of frost grape are characteristically broad and heart-shaped, which turn striking shades of yellow to red in the fall. Clusters of small, inconspicuous flowers precede the development of small, blue-black berries that may be present on the vine. The bark of the vine peels in vertical strips, adding texture and visual interest.

Flower Features

The flowers of frost grape are small and inconspicuous, typically greenish or yellowish-green. They bloom in dense clusters known as panicles, which measure approximately 6 inches (15 cm) in length. Each flower has a small, star-like shape with five petals that are fused at the base. The blooming period occurs from May to June. While the flowers are not particularly noted for their fragrance, they play a crucial role in the pollination process, leading to the development of the plant's fruit.

Stem Features

The stem of frost grape is robust and thick, often forming a trunk up to 4 inches (10 cm) across at the base of mature, multi-stemmed plants. The bark tends to be rough and may exhibit a texture that supports the growth of lichens, presenting a rugged appearance. The coloration of the stem ranges from a dark brown to grayish hue. Branching is extensive, with older stems becoming more gnarled and woody, contributing to the vine's vigorous climbing habit.

Fruit Features

The fruit of frost grape is a small, round berry typically measuring about 0.4 inches (1 cm) in diameter. These berries mature to a deep blue-black hue and possess a frosted appearance due to a natural waxy coating called bloom. The fruits cluster on cymes and each contains a few small seeds. They are known for their sweet yet tangy flavor and have a fleshy, juicy pulp. The berry's skin is thin but can be slightly tough, contributing to the overall texture.
