About Amethyst
Gumdrop-shaped silver cones and long, thin silver bracts become silvery blue. Serrated leaves are green with lighter veins and fringed edges.
From the parsley and carrot family, sea hollies are not related to the hollies or thistles they somewhat resemble. They look great with small ornamental grasses and with yellow flowers.
About Sea Holly
Offbeat, fanciful plants seem to be from an alien planet. Minute flowers are packed into small cones with a collar of spiny bracts (petal-like leaves) so that the whole resembles a bizarre daisy. Stiff, branching stems with prickly leaves. Color remains when cut or dried. Best in hot, full sun and actually likes poor, dryish soil. Drought-tolerant and deer-resistant. July–September.
