Caltha leptosepala
white-flowered marsh marigold
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.

How to care for Caltha leptosepala:
Plant Caltha in consistently damp or boggy ground, ideally in humus-rich, neutral to slightly acidic soil at the edge of a pond or stream. It can also be grown in shallow water up to 10cm (4in) deep, using our aquatic basket option to help contain roots.
Choose a sunny or partially shaded spot. Water boggy situated plants well during dry spells, especially in the first year after planting. After flowering, cut back spent growth to encourage a possible second flush in autumn. Every few years, lift and divide overcrowded clumps in late spring to maintain vigour.
