Eryngium (or Flat Sea Holly) is known for its unusual spiny leaves and dome-shaped flower umbels, with an appearance similar to thistles. The silver blue stems and flower heads are sought after primarily by cut flower growers who are looking to add interest and texture to their cut flower product line, either fresh or dried. However, experienced home gardeners will also find these plants to add diversity to their perennial gardens. Plant blooms early to late summer.

The Harris Seeds company began catalog operation in 1879. It evolved from the efforts of Joseph Harris who was extremely successful in the selection of superior strains of vegetables and grains. The company became wildly popular because of his basic business philosophy - "Offer my customers a quality product at a fair price and they will return."
