Money doesn’t grow on trees in Brown County, but wisteria does. Long ago, Selma Steele planted the wisteria that covers this pergola with lavender blossoms each spring. This year it is blooming exceptionally early, along with the lilac in the foreground and the dogwood in the background.
Three species of wisteria grow in the U.S. including a native one, W. frutescens, but the Japanese and Chinese types are more common — and more invasive. Wisteria is a fast-growing vine that can reach up to 30 feet tall when supported. Unfortunately, when your house becomes the support, battle lines (and pruners) must be drawn. It’s hard to keep ahead of the rapid growth as creeps under shingles and twines around nearby trees.
Those unfamiliar with the plant might ask the name of this beautiful ‘tree’ (in the photo to the left) but it is just an ‘escaped’ wisteria, climbing up at the forest edge (to the detriment of the actual tree).
One way the vigilant gardener can enjoy this beautiful vine is by training it into a shrub form. By careful pruning and lots of patience, this can be the result:
There’s still time to enjoy these blooms close-up, but hurry or you may have to ‘settle’ for masses of peonies and iris instead. I encourage you to visit T.C. Steele State Historic Site this spring. Like wisteria, it will grow on you.
