Dicentra formosa var. stuart boothman

This is a woodland perennial with creeping rhizomes. It is capable of making large drifts in the leaf litter beneath deciduous trees. The foliage is very finely cut and has a silver sheen. Dusky pink flowers sit above its foliage over the spring months.
As with most woodland perennials the rhizomes like to spread just beneath the mulch so a good thick layer is beneficial.
