Marginal plants such as water irises, marsh-loving varieties, dwarf papyrus, rushes and sedges work well on shelves or in shallow water around the edges.
For planting on the pond edge, think in layers. Ornamental grasses bring movement and softness. Agapanthus, wild iris and dietes add structure. Verbena, bergamot and other flowering perennials help attract pollinators, while low groundcovers between rocks make the pond feel settled into the garden.
The best ponds usually combine all of these, with underwater plants for balance, surface plants for shade, marginals for structure and edge planting to tie the feature into the rest of the garden.
WATER MOVEMENT HELPS
Still water can be beautiful, especially when it reflects the surrounding planting and sky, but some movement makes a real difference to pond health. Circulation improves oxygen levels, reduces stagnant patches and helps keep the water fresher and clearer. It can also stop organic matter from settling too heavily in one place and turning into sludge over time.
