Growing at a glance…

Cut back eryngiums when their blooms begin to fade, as this will help encourage future growth. Plant in well-dug and prepared soil. Protect them from excessive winter wet. Ideal for planting in containers and front of border displays. To plant loose roots, soak them in a bucket of water for 1-3 hours before planting, then dig a hole in the border that’s big enough to house the root system. Firm in gently and water well.
