Eryngiums make a striking addition to dry, sunny borders and gravel gardens. They have thistle-like flowers, made up of tiny flowers packed together in a tight cluster, surrounded by a ruff of spiny bracts. The flowerheads last well when cut and can also be dried.
Eryngium planum 'Jade Frost' is a relatively small sea holly with green, cream-edged leaves and flowerheads that start out off-white before turning a rich indigo tone. It's perfect for growing at the front of a herbaceous border, gravel garden or in a container, and makes a wonderful cut flower, both in fresh and dried arrangements.
For best results grow Eryngium planum 'Jade Frost' in free-draining soil, in a sunny position. Protect from excessive winter wet. Find out more on our grow guide for Eryngiums.
