Eryngium planum 'Blue Cap' PPAF

Sea Holly

'Blue Cap' ('Blaukappe') Sea Holly blooms in July and August, producing silvery blue spiky flowers in abundance.  The unusual cone-shaped blooms are held on thistle-like silvery foliage and are attractive to butterflies and other pollinators.  The flowers dry well and are used for floral arrangements.  Eryngium 'Blue Cap' performs well in hot dry areas and is salt tolerant, so seashore locations are a perfect place for this unusual perennial.
