A severely underrated group this. This bushy species has narrow green foliage and heads of large dark inky purple flowers. You can see where the common name comes from.
Endangered in the wild but easy in the garden given normal ‘alpine’ conditions. Very special.

Dracocephalum rupestre and/or grandiflorum
A compact leafy herbaceous perennial producing a mound of rounded green leaves with rich purple ‘Dragon Heads’ on short reddish stems above. For a well drained (but not too dry), sunny (but not too hot) site, if that makes any sense. Basically a large alpine. I've had seed of this as both D.rupestre and grandiflorum and they seem identical. If anyone can let me know how to tell which is which I'd be grateful.
