THE FLOWER GROWER'S GUIDE. 



marsh marigold (Caltha palustris), bog bean (Menyanthes trifoliata), water dock 

 (Rumex hydrolapathum), bulrush (Typha latifolia), water irises and the like, are all 

 suitable. These ought to be arranged in groups rather than in a general mixture. 

 Not only are they most effective in masses, but unless kept well apart, the robust will 

 soon destroy the weaker kinds. 



What are known as bog plants are those that will neither thrive in water nor in dry 

 ground. They require to be planted in a mixture of black peat, leaf soil, and other 

 decaying vegetable matter constantly moist, yet not submerged. Many interesting, and 

 to a certain extent beautiful plants, luxuriate under those conditions, and the wonder is 

 that so few owners of gardens where a collection of bog plants might be formed, have 

 so neglected their opportunities ; all they need are water-holding beds, which may 

 be in the form of terraces on a slope, or on a level with a brook or ditch of running 

 water. 



The sides and base of the beds should be either concreted or bricked and cemented. 

 A depth of 12 inches suffices, and this may be nearly half filled with stones covered 

 with G inches or rather more of black peat and leaf soil, some of this being formed into 

 ridges with stones. There must be an outlet for the water, which may be returned to 

 the stream from whence it is drawn, or be run into the lower beds and from thence to a 

 pool formed for the true aquatics. Moisture will rise to the surface of the beds and 

 keep the peat constantly moist. The ridges and crevices between the stones are the best 

 positions for those kinds of plants requiring the least moisture, such as osmundas in 

 variety, Struthiopteris pcnnsyivanica, Onoclea sensibilis, Cypripedium spectabile, 

 dodecatlieons, Dielytra spectabilis, dryas, pinguiculas, sarracenias, various piimulas 

 and Iris fulva. Ehododendrons, kalmias, andromedas, and bambusas, are also well 

 adapted for planting in the higher drier parts of the bog garden. 



The appended list of aquatic and bog plants should be of service in showing 

 what may be grown in the various positions indicated.
