The Japanese Wisteria or Wisteria floribunda is as the name suggests a native climbing plant of Japan that was imported to America in the early 19th century. The Rosea is one variety of Wisteria floribunda with long racemes of flowers, up to 60cm in length, a delicate scent and pale rose pink in colour which would make a stunning addition to any garden with room for it to develop. Growing in a clockwise fashion the woody stems will almost certainly need support in the form of a framework such as a pergola or straining wire and although not necessarily attractive through the winter months this is more than made up for by the volume of cascading foliage and flowers in late spring and early summer. Wisteria floribunda Rosea is also occasionally used as the subject for bonsai.
Wisteria are very long lived plants, Wisteria floribunda Rosea can be slow to establish but with these grafted plants earlier flowering is assured. It will flourish and flower better in a sunny site but will tolerate a little shade in moist, reasonable soil and if sheltered can cope with fairly low temperatures. If space allows it can grow to over 30 metres long but needs to be pruned each year to be kept into shape and to encourage flower growth for the following season.
Supplied as pot grown, Wisteria floribunda Rosea can be planted at any time of the year with no trauma to the root system so it will bed in quite quickly and hopefully reduce the amount of time to flowering.
