Culture

Easily grown in dry to medium, gritty, well-drained soils in full sun. Tolerates some light shade. Tolerates poor soils.

Noteworthy Characteristics

Moroccan sea holly is a clump-forming, evergreen perennial that is perhaps best noted for its glossy, white-marbled foliage and its thistle-like grayish-blue flower heads. This is a somewhat coarse plant that features basal rosettes of oblong, cordate-based, serrate, dark green leaves (to 2” long) that are marbled with white. Smaller, spiny-lobed stem leaves. Tiny, grayish-blue flowers tightly packed into egg-shaped heads (umbels) resembling thistles appear in summer in branched clusters at the top of stiff, branching stems rising from the centers of the basal rosettes to 12-16” tall. Each flower head is subtended by a narrow, spiky collar of pale blue bracts (to 1” long).

Problems

No serious insect or disease problems.

Garden Uses

Rock gardens, borders and beds. Perhaps best massed or in small groupings.
