Bog garden

From Gardening Wiki

A bog garden is a wet one, more or less faithfully reproducing boggy conditions. It is just the place for segregating some of the orchids, ferns and other native plants that otherwise are liable to perish in cultivation, or at best grow only half-heartedly. It may be also a peat garden, or just the moister section of one the remainder to be higher land for rhododendrons, heather, lilies and other peat-loving plants.
