Blue Wisteria dripping off porches, archways and the frontages of country cottages is a wonderful sight of spring and early summer and fills the air with sweet heady perfume. Wisteria grow vigorously and can reach heights of 10m if left unchecked but can be pruned to restrict if space is limited. The plant is easy to grow - just give it in a sunny spot with support to allow the twining stems to climb - trellises and pergolas are perfect for this. Once established you'll enjoy a profusion of fragrant blossom from April to June and the bean-like seed pods that follow are a lovely bonus. Pruning is easy, just shorten the new growth in August and again the following February.
