Sea holly (Eryngium planum 'Blue Glitter') requires full sun to thrive. It should be placed in an area that receives at least 6 hours of direct sunlight each day. During the summer months, it can tolerate a few hours of midday shade as well, but should have full sun for the remainder of the day. The plant will do best in a spot that is sheltered from strong winds. In winter months, the sea holly may require a few hours of morning sun and afternoon shade to protect it from the intense midday rays.

Sea Holly (Eryngium planum 'Blue Glitter') should be pruned in the early spring, before new growth begins, in order to maintain its desired compact size and shape. Pruning should be done by removing any dead or dying stems and cutting back any overly long stems. This will help to stimulate new growth and promote a bushier plant. Prune back lightly, as heavily pruned specimens may be slow to recover, or may not recover at all.
