This showy and pleasing plant is only seen in highest perfection on elevated banks, rubbish-heaps, or old walls, in which positions it endures much longer than on the level -round, and becomes a long-lived perennial with a shrubby base. On the long bridge across the Nore at Col. Tighe's place, Woodstock, Kilkenny, it grows in abundance, forming a long line on the wall above the arches ; of course it could be easily grown on ruins, while it is invaluable for banks of all kinds, chalk pits, etc., and also for the level ground, except in heavy cold soils. Some of the larger Valerianas would grow freely in rough places, but none of them are so distinct as the preceding.
