Dicentra is a genus of eight species spanning annual and perennial forms, all members of the poppy family and all sharing the same characteristic lacy, deeply divided foliage that earns them constant comparisons to ferns. Native to moist woodland areas across North America and western Asia, they inhabit the kind of shaded, humus-rich ground that challenges most ornamental plants. Their two-toned, heart-shaped flowers in pink and related shades arrive as welcome proof that deep shade need not mean dull planting.

Growing to about a foot tall and wide, they are best placed at the front of a woodland border or tucked into an understory planting where their delicate texture contrasts with bolder foliage. Rich, moist, well-drained soil in partial to full shade suits them well. Maintenance demands are minimal, and they are reliably resistant to deer. All parts are toxic if ingested.
