Aquatic and marginal plants should be placed in pond plant baskets filled with aquatic soil (sold separately) and topped with a thin layer of gravel to help prevent the soil from washing away. This plant is suitable for zones 1 & 2 of a pond.
Caring and Maintenance:
This is a very low maintenance plant which requires a well moisturised environment. Propagate by division in spring. Small divisions should be placed on a cold frame until they are well rooted.
Please Note: All parts of the plant are poisonous.
Plants from the Ornamental collection grow naturally in shallow waters and at the edges of ponds. Low growing rafting types have charming flowers and attractive foliage, whilst tall emergent plants add structure and should be planted at the far side of the pond or water feature. There is a wonderful variety of ornamental marginal plants available, with their flowering times ranging from as early as February through to October.
