This deciduous perennial unveils a striking display with glossy, dark green, heart-shaped leaves that provide an elegant backdrop to its yellow-centred white flowers, each boasting a diameter of up to 4cm (2”) in the spring. Notably less vigorous than its native marsh marigold counterpart, Caltha leptosepala prefers boggy conditions over full submergence in water but will tolerate shallower areas of a pond. Perfectly suited for stream and pond margins, it brings a touch of sophistication to the water's edge, where its subtle beauty can be admired.
Plant in reliably 'boggy' ground in humus-rich soil at the water's edge, or in shallow water up to 10cm (4") deep. Low maintenance, Caltha will often re-grow and flower again in autumn if cut back hard in summer. Lift and divide large clumps in late spring.
