Dicentra cucullaria aka Dutchman's Breeches

Dicentra cucullaria is a small perennial called Dutchman's breeches. It belongs to the poppy family, Papaveraceae. Its native range covers eastern Canada and northern and eastern America. It grows in woods, ravines, rocky slopes, and stream edges. This woodland plant makes its growth in spring. Its leaves die back by summer, leaving a seasonal gap.

Garden plants reach about 0.5–1 foot [0.15–0.3 metres] tall. They spread to about 1 foot [0.3 metres]. RHS gives a broader upper size of 1.6 feet [0.5 metres]. The plant forms small clumps but can cover larger areas. Leaves and flower stems rise from a scaly rootstock. The grey-green leaves have deep cuts and a fernlike look. They form a basal group on long stalks. Smooth stems range from tan to reddish brown.

Flowers appear from March to May, depending on the site. Each arching, leafless stem holds a row of hanging blooms. Most flowers are white, though some have a pink tint. Their tips range from yellow to greenish yellow. Two swollen petals form spurs, giving each bloom its trouser shape. The flowers have scent and attract bees. Brown seed capsules form in May and June. They split into two sections and release many seeds. Ants carry seeds away to eat their attached food bodies. They then discard the seeds, helping the plant spread.

Grow it in partial or full shade with good drainage. It needs humus-rich soil and moderate moisture during growth. Sources support clay and loam, with differing views on pH. NC State recommends acid to neutral soil. RHS favours neutral to slightly alkaline soil. Avoid wet soil in winter, which can threaten survival. RHS advises keeping it nearly dry during summer dormancy. Dry soil can bring leaf dieback forward. It suits USDA zones 3–7 and has RHS hardiness H5.

Woodland, shade, and native plant gardens suit its short season. Later-growing perennials can fill the gap after its leaves fade. Its summer absence makes it less useful in lasting borders. Deer and rabbits tend to leave it alone. Aphids may attack, while slugs and snails can damage new leaves. Serious disease problems are uncommon, and it needs no pruning. No edible uses are known. All parts can cause harm when eaten in large amounts. Symptoms can include vomiting, shaking, fits, and breathing trouble. Sap or leaves can also irritate skin. Historical medicinal uses do not make it safe to consume.
