Marginals

Marginal plants are key for creating a healthy balanced pond, as well as providing height, colour and interest to your planting scheme. These plants will attract a variety of flying insects, whilst their foliage will give aquatic wildlife shelter for hiding and nesting.

True marginal plants can tolerate waterlogged soil, or water over their crown, all year round. They are typically found around the margins of ponds, in shallow water. When planting marginals it is important to refer to the recommended planting depth. This refers to the depth of water tolerated above the crown of the plant, typically the depth of water above the soil level. A plant that prefers a planting depth of 0-10cm can be grown anywhere from waterlogged soil (0cm) up to 10cm of water above the crown.
