Wisterias [wis-TEER-e-yas] are sturdy
woody vines with graceful foliage and spectacular cascading
flowers. Members of the pea family, they have always been landscape
favorites of homeowners. Perennial plants, they bloom for many
years. Many persons regard wisteria as the premier ornamental
vine. Wisterias are beautiful and easy to grow. While there
are several types of wisterias, Japanese Wisteria (Wisteria
floribunda) is one of the most popular in northern yards and
gardens.
Size:
Japanese wisterias climb to 30 feet or more, and spread as far
as they're allowed. They spread vigorously, twining from right
to left around their support.
Foliage:
Leaves of Japanese wisteria are made up of 13 to 19 small leaflets
that are arranged along thin leaf stems. The leaves are dark
green over the season, turning to yellow in autumn before falling
at frost.
Flowers:
Individual Japanese wisteria flowers are like pea flowers.
They
hang in magnificent clusters up to 36 inches long. Typically
they are deep violet. Emerging in late May just before the leaves
come out, the tiny flowers open progressively from the base
of each cluster to its tip. They bloom over a period of 4 to
5 weeks in the spring, their heavy fragrance permeating the
landscape. Some varieties have white, mauve, or pinkish flowers.
The flowers give way over the season to long, furry green bean
pods that hang on the vines all winter. The pods are not edible.
