Plant Information
Culture Easily grown in dry to medium, gritty, well-drained soils in full sun. Tolerates some light shade. Tolerates poor soils. This is a taproot plant that transplants poorly and is best left undisturbed once established. Plants do not spread. Foliage is evergreen in warm winter climates. May be grown from seed. Noteworthy Characteristics Eryngium variifolium, commonly called 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).
