Plant some Dicentra!

Dicentra, Lampracapnos, Bleeding Heart, Lady in the Bath (you'll need to turn the flowers upside-down for the last one to make any sense) ...

Whatever you know them as, find some room in your garden for one or more, as they are a great early-season perennial.

Pink 'Dicentra spectabilis' is happy in shade or sun, while the white version actually prefers shade. They will make a good show until late May, when they will die back (be sure to mark where they are with a label as they die down completely), making them great for pairing with late-flowering perennials such as Penstemons, Fuchsias and Dahlias. Next spring expect them to pop back up covering twice the space.
