Bog gardens are a unique type of garden characterized by the presence of bog plants that thrive in wet, acidic soil conditions. The term "bog garden" can be used interchangeably with other phrases such as "wetland garden" or "marsh garden". Another similar term is "water garden", which typically refers to a garden filled with aquatic plants and features, but can also include bog plants. "Fen garden" is another synonym for this type of garden, specifically referring to wetland areas with peat deposits. "Swamp garden" is also used to describe bog gardens, although swamps are typically characterized by standing water, while bogs have more sphagnum moss and standing h2o is less common.
