Description
Eryngium planum
Dazzling sharp, dynamic texture adds intrigue in the garden and in flower arrangements.
Amid a sea of green, the spiky flowers of sea holly really do sparkle like steel-blue glitter! Hardy, heat- and drought-tolerant plants grow 3’ tall and make striking cut flowers who shine in fresh and dry everlasting bouquets. Growers Swift River Farm report visits from an array of unusual pollinators who can’t get enough that blue glitter love!
Seeds grown by Swift River Farm in Salmon, Idaho.
40 seeds.
Directions: Direct seed in fall, or cold stratify in damp sand in the fridge for 4 weeks then sow outdoors in spring or sow into pots indoors. Will flower the second year.
