Bladder Senna

From LoveToKnow Garden

Bladder Senna (Colutea) - These cannot be called choice flowering shrubs, but they are very useful for poor hungry soils, particularly for dry sunny banks, where few other plants can exist; they are excellent, too, in smoky districts. Like the Gorse and a few other shrubs of the Pea family, they delight in a dry, sandy soil, and when in flower, which is during several weeks in late summer and in autumn, they are pretty, their foliage being light and elegant. They have numerous names, but there are only one or two distinct kinds. The commonest is C. arborescens, which, under favourable conditions, grows 6 or 8 feet high, has large flowers, varying in different varieties from yellow to a deep reddish-yellow. C. cruenta, C. halepica, and C. media—all natives of Europe—are smaller, and have bright yellow flowers; but all have much the same aspect.
