Marginal & Bog: Hardy
Hardy Marginal and bog plants are plants which are not fully aquatic, but rather they live either around the pond area in moist earth or they live "feet wet" meaning they actually live with their lower roots and vegetation under water but the leaves of the plants remain above the water and dry. These plants will survive colder weather in many states, either by dying back and re-growing in spring or by going dormant. Extreme cold may kill these plants. Cattails are among the most popular and well known hardy marginals.
