Wisteria the double agent. It pretends to be a vine, but it’s really a tree. This one is growing in my friend Lory’s garden and is quite spectacular as it winds its way up a Western Red Cedar. She said this wisteria has been growing here for about 17 years.
Chinese wisteria (Wisteria sinensis) is the most popular form. It twists in a counterclockwise direction and blooms with long racemes of purple flowers in May, before the leaves have arrived. The flowers have a sweet scent that is delicious as it drifts through the air. Japanese wisteria (Wisteria floribunda) twists clockwise and the blooms are longer than Chinese wisteria, opening slowly from the base towards the tip of the raceme. These plants are in a hurry. They can grow 25 feet in one year which means they will need a lot of pruning to keep them in check. Not a plant for wimps!
