Common white jasmine (Jasminum officinale) is also referred to as Poet's jasmine and grows to a height of 10 to 15 feet. It demonstrates a medium rate of growth, accumulating between 13 and 24 inches annually. When grown as a vine, the branches must be supported, with cultivation as a shrub requiring extensive pruning. The vine produces fragrant, white flowers, approximately 1 inch in width. Common white jasmine prefers full sunshine with a mix of partial shade.
Although its name states otherwise, Confederate jasmine is not a true jasmine at all; instead, it is a member of the Trachelospermum genus, a family distinctly different from the jasmine. Still, it is commonly referred to as a jasmine and widely planted and enjoyed due to its vibrant flowers and strong fragrance. The vine reaches up to 20 feet in length and sports dark green leaves nearly 3 inches long, with white flowers that clump together.
Winter jasmine (Jasminum nudiflorum) is a viney shrub that drops its leaves in the fall and grows to approximately 7 feet wide and around 4 feet high, even without support.

The flowers may begin to appear in late winter or early spring, even before the green leaves begin to develop.
