Caltha palustris polypetala Giant king cup

Description

A much bolder plant than Caltha palustris with striking, large, single yellow flowers that appear in early spring and continue for longer than other Calthas. Mature plants frequently have a few flowers throughout milder winters.

Repotting or planting

9cm marginal plants require potting into a larger mesh basket. Place in a pond no deeper than 1/3 maximum recommended planting depth to allow the plants to establish. 1ltr marginal plants do not require repotting, place in the pond no deeper than 1/2 maximum recommended planting depth to allow the plants to establish. 3ltr and 5ltr plants do not require repotting, as they are larger more established plants they can be placed up to the maximum recommended depth. There is no need to remove the mesh basket.
