Quite a large number of plants are now stocked by certain nurserymen to meet the demand that has arisen of late years for the furnishing of banks of lakes, ponds, streams, etc, and also for the water itself. Plants that flourish on the margins in marshy spots are known as bog or marsh plants, while those actually growing in the water are called "aquatics". Every large garden, private or public, now has a water garden and a bog garden, and wonderful taste is displayed in rendering them beautiful objects in the landscape. The following genera supply plants that flourish, under conditions mentioned, in the open air, the purely aquatic ones being indicated by an asterisk (*) and the more or less tender ones by a dagger (†).
