Muscadine grapevine plants can grow up to 60 ft tall in nature when supported in trees, but if left unsupported will only grow 3-4 ft tall on wobbly weak vines. The leaves of muscadine vines are heart-shaped, light green in color and have wide teeth that grow along the edges of the leaves. The muscadine grape vine plants are considered to be cold hardy, and the vines are not significantly damaged unless temperatures fall below minus ten degrees Fahrenheit.
A male muscadine grapevine must be planted along with a female grape vine in order to produce grapes. The female muscadine grapes are larger than the male grapes, so that the female muscadines are considered to be more important products for the best consumer shelf appeal at the grocery store.
