Regional Picks: Big Blooms That Don’t Flop – Mountain West

Fine Gardening – Issue 156

1. ‘Big Blue’ Sea Holly

Name: Eryngium ‘Big Blue’

USDA Hardiness Zones: 4 to 9

Size: 28 to 30 inches tall and 15 to 18 inches wide

Conditions: Full sun; sandy to average soil

‘Big Blue’ sea holly is the perfect plant for our challenging conditions. Hail and drought do not affect it, and it loves sun and lean soil. The plant’s form alone is dramatic enough but then it adds the blue flowers, which extend up the stem and finish with a spiked 4-inch-diameter collar. This is a nonstop bloomer from its first flower in midsummer until early autumn. Deer and rabbits avoid it, but bees swarm the blooms.
