Eryngium planum 'Deep Blue' - sea holly

DESCRIPTION: Branching perennial with slightly spiny grey-green holly-like leaves and long stems topped with dense button flowers in steel-blue. Loved by beneficial pollinators such as honeybees and butterflies. Makes a good cut flower for the home, and an impressive addition to a modern or traditional garden. Very cold tolerant and drought tolerant once mature.
PLANTING: Sow seeds in Spring-Summer directly into final position or in seed trays/pots, and keep moist. Sow on the soil surface and press down. Germination can take from two weeks to three months; a spell of cold can help.Thin plants once they develop 2-4 leaves and are easily handled. Plant in free draining soil in a sunny location for best flowering.
CARE: Water seedlings regularly until established and continue to provide water especially during dry spells. Mulch plants to keep the shallow roots cool in summer. For an extra long flowering season, remove spent blooms and feed with liquid fertiliser.
