This rosette forming biennial is great for the front or middle of a sunny, well drained border. The attractive foliage is displayed to best advantage if the plant is mulched with or planted in gravel. A biennial plant, it will die after flowering in its second year, but self seeds freely in a good spot, thus ensuring more will follow. Garden care Lift and divide large colonies in spring. Avoid the temptation to cut back the flowerheads in autumn as they provide interest in the winter garden.
