Description As a native of Asia, there are a number of different cultivars of Woodbine Honeysuckle. The cultivar ‘Graham Thomas’ has white to light yellow flowers.

  Morphology:
This is a deciduous twining vine that can grow 10’-20’ with medium texture and a fast growth rate. Leaves are arranged in an opposite fashion. They have a ovate shape and are typically 2”-2.5” long and 1.5” wide. During the summer the foliage is dark green. There is no remarkable fall color.
Flowers first appear in late spring and continue into the fall. They have a tubular shape up to 2” in length. They start out white but morph to light yellow as they age. They have no real fragrance. The flowers are attractive to hummingbirds.
