Hybrid selected by Mr. A.J. Hancock where it lines walls and terraces of Powis Castle in Wales. Blooms in late summer, but flowers inconspicuous. Wormwoods are reported to be medicinal, the leaves and flowers providing a strong stimulant in drinks, but known to produce toxic effects in humans who drank it. Silvery foliage and dissected, pinnatifid leaves provide identification problems with group of plants known as dusty millers.
