'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.  Eryngium 'Blue Cap' performs well in hot dry areas and is salt tolerant, so seashore locations are a perfect place for this unusual perennial.
