I wonder why nurserymen do not send out small trees of this plant grafted on the varieties of the locust. It takes and grows thereon as vigorously as does the apple on its kind. On a stock, anywhere from one to six feet high, it forms a graceful head of lovely bloom and foliage. There are two, perhaps more, varieties. The old, with flowers of a dull purplish pink, and the major, much the finer in flower and foliage, blooming in long racemes of bright, clear and most delicate pink, very pleasantly fragrant.
It blossoms at the same time with Laburnum and Wistaria. A group thereof in grace, in tint, in fragrance and entire loveliness, would have no rival. For some reason the dwarf nature of the Rose acacia seems to stay the rambling, sucker-ing propensity of the locust roots. At any rate, I have never been troubled by this habit under Rose acacia grafts. To have a compact head and fine blooms, cut in pretty boldly in the early spring. It blossoms on the shoots of this year. After the first flowering a like treatment will give you a late bloom. If possible, give to this plant, the Wistaria, and the Laburnum a plentiful supply of water when in flower, thereby their bloom is finer and holds longer.
