Marginal Plants, Perennials or Woodland Ferns?

Marginal Plants, Perennials or Woodland Ferns?

Marginal plants are so called and categorized for a good reason. Simply put, they grow at the water’s edge (water margin) where land meets water. It is important to bear in mind that in natural clay or silt based ponds, the water margin will rise in times of flooding and sink in times of drought. This natural rise and fall in water levels also happens to a lesser degree in man-made concrete ponds, preformed  fibre glass ponds and butyl rubber lined ponds. Accordingly, in natural ponds, true marginal plants are quite adaptable and have different ways of dealing with extremes of seasonal weather. For example, some produce long roots that will always find the water table, while others in times of drought will self-seed and germinate and colonize when the natural water levels rise again.

However, this natural rise and fall in water levels also happens to a lesser degree in man-made concrete ponds, preformed  fibre glass ponds and butyl rubber lined ponds. Therefore, marginal plants for these ponds must also be adaptable to changing water levels.
