The first is Decentra exima with it's ferny leaves and more elongated flowers.
This one is Dicentra 'Gold Heart', though it's the leaves that are gold, actually, not the heart-shaped blooms.
Dicentra 'Burning Hearts' is rather new in the Hollow. Very pretty red.
And the first one we got, the old fashioned Bleeding Heart
The white version is a bit less robust and doesn't increase as fast, but is just lovely.
And last, but not least, is 'Spring Magic' We have had this for many years and it is still just a small clump. This one is a much more petite Dicentra, only about 10-12 inches tall and the most lovely shade of pale pink.
These all like shade and woodsy soil. On years with hot summers, they will go dormant by mid summer. On more moderate years, the foliage will persist, though the bloom is only in the spring
