Eryngium (Sea Holly)

Attractive, Sea Holly plants (Eryngium) are striking ornamental perennials grown for their arresting, thistle-like, silvery or blue tinted flower heads adorned with a ruff of showy bracts. Blooming in summer and sometimes into fall, they are useful in rock gardens, coastal gardens and in borders where their steel blue flowers and foliage complement the vibrantly colored summer flowers.

• Their beautiful texture, unique color, long-lasting flowering and remarkable qualities as cut flowers make them a favorite of florists, gardeners, bees and butterflies. They are exceptionally care-free plants if they are given a well-chosen site.
• With a trend toward drier summers, Eryngium has become even more popular. Easy to please, even in dry gardens where other border stalwarts suffer, Eryngium goes from strength to strength over the entire summer, complimenting every other plants with its silvery or metallic blue flower heads.
• Drought tolerant, Sea Holly also handles salt spray with ease.
