Eryngium planum ‘Jade Frost’

Variegated Sea Holly

USDA Zone: 3-9

Plant number: 1.205.260

Sea Holly features open umbels of prickly flowers which are a favourite for cutting, fresh or dried. This unusual selection has grey-green leaves edged in creamy white, developing pink tones during the cooler months. Stems and flower clusters are a rich violet blue, appearing in early to midsummer. Tolerant of hot, dry sites, and soils high in salts. For drying, pick stems just as the flower clusters open fully, and hang upside down to dry in a warm, dark place. Attractive to butterflies. Found in the Cornwall, UK garden of James and Megan Cave. This is pretty much the first and only variegated Sea Holly to be commercially available. USPP#17370: unlicensed propagation prohibited.
