A common wild plant, but not without beauty; it is frequent on old walls, and has yellow and sweet-scented flowers. The stalks are woody, and a foot and half high; the leaves are very numerous, longish, narrow, and of a dead green. The flowers stand in a kind of spikes, at the tops of the stalks, and are yellow and moderately large. The seeds are contained in long pods.
The flowers are used; and an infusion of them fresh is good against the head-ach, and in all nervous disorders. They are also good to steep in oil, to which they give a cordial warmth, and make it good against pains in the limbs. But they are not either way much used at present.
