About Eryngium bourgatii 'Picos Blue'

Eryngium bourgatii 'Picos Blue' · also called Picos Blue Mediterranean sea holly · flowering

'Picos Blue' is a compact Mediterranean sea holly prized for intense violet-blue flower cones and silver-veined, deeply cut basal foliage. A tough, sun-loving, drought-tolerant perennial from Spanish mountain origins, it suits gravel gardens and dry borders. The spiny bracts attract bees and dry beautifully, giving long-lasting summer structure and colour.

Ideal humidity: Outdoor ambient

Watch for — Root and crown rot: Wet or poorly drained soil, particularly in winter, rots the crown. Provide gritty, sharp drainage and keep the base dry.

The base rhythm for eryngium bourgatii 'picos blue' is minimal once established; only during extended dry spells, roughly every 2-3 weeks, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
