Like our native marigold, this plant is clump-forming and easy to grow, producing attractive ivory-white flowers with yellow centres and brightening up the pond early in the season. Its more compact size makes it suited to smaller ponds where the native marsh marigold may be too large. If cut back after its spring flowering, it will produce a second, lighter, crop of blooms in late summer/autumn as well.
Looking at the Latin name of this plant, you would assume it is simply a white-flowered variant of our native yellow marsh marigold. However, it is a noticeably different plant - smaller (more like the double marsh marigold in size than the native one) and with leaves which are flatter and have toothed edges. More importantly, it prefers a drier location than the standard yellow marigold - it will tolerate a little water over the soil, but it does not like water over its foliage, so it is somewhat between a marsh plant and a pond plant. It is not found in the wild in the UK, and is considered to be native to Asia, hence its alternative name of 'Himalayan Marsh Marigold'.
If designing a planting scheme, we recommend approximately 2 Caltha palustris var. alba plants per square foot of ground, or 1 plant per linear foot of pond edge. Read more on how to pot and care for your plant.
