Less showy in terms of flower size than E. x zabelii cultivars, by contrast E. x tripartitum is far more prolific. Producing a cloud of blooms, each with a steely blue central cone encircled with pointed silvery bracts on blue multi-branched stems, its striking display lasts from mid to late summer.
A perfect choice for a wildlife garden by the sea as bees love it and it is salt tolerant, it also looks amazing planted in drifts through a gravel garden. Like many forms of sea holly, it needs full sun in a free-draining, poor to slightly fertile soil to thrive. Protect from winter wet.
