Wistaria. - This genus was formerly included in that of Glycine, but has been separated from it, and named by Nuttall in honor of Dr. Caspar Wistar.
Wistaria Sinensis. - The Chinese Wistaria. - This is one of the most magnificent climbing shrubby plants in cultivation. It was formerly treated, at the North, as a tender plant, and might be seen trained to the rafters of the green-house, in full flower, in March, with its thousands of rich clusters, or pendulous racemes of delicate pale-purple blossoms, so numerous that the whole space it occupied seemed to be' covered with them. Each raceme is from ten to twelve inches long, and densely filled with its delicate and richly perfumed flowers. It is easily raised from cuttings, or layers. In the open ground, we have known it to make a growth of twenty-two feet in one season; and, with us, has not failed, excepting one year in the last twelve, to produce an abundant bloom, and that without the least protection. The December previous to the year in which it did not bloom was a very warm one. The buds prematurely started, and were winter-killed; it, however, flow-ered in August, but not so perfectly as it should have done in the spring. The flowers make their appearance before the foliage starts, the last of May, in the open ground. The foliage is abundant, and its color is a lively, pleasant hue of green. The plants for the few first years are somewhat tender, at the North, and should be laid down before winter sets in, and covered with earth, or coarse manure. It grows freely in almost any soil; but to have strong plants, it is important to have a rich, deep loam. It will not flower till the plants get strong.
A new variety, with white flowers, was brought to England from China, by Mr. Fortune. In planting out young vines, they should be cut down to a single bud.
My plants generally produce scattering clusters of flowers, during the last summer months, but are not equal to the clusters produced in the spring. They are planted against a bank wall, on the south side, and run in and out of it at pleasure, sending out long branches in every direction, making free with all the trees in the neighborhood, and running at random in a strange manner. The wood needs shortening in February, or perhaps it would be better to prune in December.
