Note. wisteria like other vines can warp wood out its shape if the structure is not sound to begin with. They are invasive and need to be pruned yearly. If you cannot do this or provide the needed 'keeping them in bounds' perhaps another vine is a better choice such as a jasmine. Just a thot...BTW, I LOVE WISTERIA! »
California landscape designer Karen Aitken chose Chinese Wisteria for a beautiful cascading effect over this bocce ball court in Morgan Hill.
The fact that it grows like a beanstalk can be a plus when looking for quick results in a landscape, Aitken says. But be sure to plant on a separate structure away from roofs and gutters and prune it every year to keep it in bounds. Anyone who has ever had a wisteria will emphasize this point with stories of vines that have taken over lesser porches and trees.
Double rows of pinkish-purple rock cress (Aubrieta deltoidea) immediately grab your eye in this garden — it looks like someone outlined the boccie ball court with a bright highlighter. With such a strong focal point, you might overlook the other purple accents in the space until you notice how well the lightest lavender wisteria overhead frames and complements the bold color below.
Keep wisteria and other vines in check. Spring's warm temperatures and damp soil can mean lush, almost rampant growth in the garden. Vines get out of control quickly in June, so it's important to check them every two weeks and train or tie any new shoots to your trellis or structure.Of course, if new shoots are growing in the wrong direction and can't be tied in gracefully, feel free to snip them off right at the stem where they start. Vines can look wild if not carefully tended.Related: Spring Planting: Wonderful Wisteria
