Erythronium dens-canis ‘Purple King’ – This Fawn Lily is more of a magenta-pink than a purple colour with flower petals that reflex backwards – in any case, it’s still quite bright for a Erythronium. These are borne from March to April over mottled foliage of milky-green with purplish-brown highlights. Best grown in shade to part shade. Grows to 6″ high. Hardy to zone 3.
Anemone nemorosa ‘Bracteata’ (syn. ‘Bracteata Pleniflora’, ‘Bracteata Plena’) – An unusual form of Wood Anemone with semi-double white blooms surrounded by green ferny bracts and often tinted purple-blue at the petal base. The flowers are borne from March to April over finely-cut green foliage that spreads by rhizomes. Grows 6″ high. Hardy to zone 4.
Corydalis x ‘Canary Feathers’ – A sterile cross of Corydalis wilsonii and C. moorcroftiana that bears bright yellow tubular flowers (from May to July) over finely-cut bluish green compound foliage. Best grown in part shade or filtered light with even soil moisture, as drought will shorten the flower display and shift the plant into dormancy. Grows 6-9″ high by 12″ wide. Zone 6.
– Bloodroot is a native of the forests of eastern North America and gets its common name from its red sap and roots. It bears single white blooms (occasionally tinted pink) from March to April before the foliage emerges. Coarse, deeply-lobed grey-green leaves take their place and eventually go summer dormant. Grows 6″ high by 12″ wide. Zone 3.
Jeffersonia dubia (syn. Plagiorhegma dubia) – This species of Twinleaf is native to northeast Asia and shares the genus with Jeffersonia diphylla of eastern North America. It bears cup-shaped upward-facing lavender-blue flowers (occasionally white) in spring over green serrated foliage that is often edged in red. Grows 8″ high by 10″ wide. Hardy to zone 5.
