Wisteria is a vine that is commonly grown as an ornamental plant. It is prized for its large clusters of hanging flowers that are fragrant and come in a variety of colors from white to pinks and purples. The leaf of the wisteria plant is compound, made up of several leaflets, and is relatively easy to identify.
Wisteria has a compound leaf, which is made up of the central stem with 13 to 19 lance-shaped leaflets.
Leaflets are positioned opposite each other along the stem with a single leaflet at the end. Leaflet pairs are spaced evenly along the stem between 1 and 2 inches apart.
Each leaf is 10 to 15 inches long. Each leaflet is approximately 1 1/2 to 3 inches long and 1/2 to 1 inch wide.
The color of the leaf is light to bright green during the growing season and merging leaves may be tinged with red. The leaves may turn yellow in autumn before falling.
Mature leaves are smooth on the top and bottom surfaces. Young leaves may have a silky texture.
