Few plants can give us the radiant blue of Diamond’s Blue Larkspur, Delphinium. Low, bushy mounds of lacy green leaves bear loose sprays of single blooms all summer long in a gorgeous electric blue shade featuring a purple spot on each petal. Ideal for containers mixed with other colorful plants or on its own.

Diamonds Blue tolerates hot, humid weather better than older varieties. Technically a perennial, yet here in St. Louis we treat it as an annual, enjoying its beautiful color for just one season.

Plant in a bright sunny location that gets a a break from the hot afternoon sun. Removing spent flowers will encourage more blooming.
