Monkshood often reminds gardeners of delphiniums since the rich blue color is the same. But its much easier to grow. First of all, Monkshood is plenty tall, but shorter than the towering delphiniums that always need staking. This one stands on its own. And its not as brittle as a delphinium, so does a simpler job of adding tall blue flower spikes to your late spring garden. The roots are poisonous.
