About Silver Ghost

Prominent green cones with frosty greenish bracts that form a showy star.

From the parsley and carrot family, sea hollies are not related to the hollies or thistles they somewhat resemble.

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.
