Saxifraga oppositifolia ; Soldanella alpina ; Verbena Lamberti, and V. 

 Arraniana, &c. Red. Silene rubella ; Lj^chnis alpina ; Pink Hepatica; 

 double red Primrose ; and Cineraria cruenta, though this last must be 

 kept in the house during winter, and only planted out after its flower- 

 buds have formed. Various kinds of Heaths, and some of the Cape 

 bulbs may be brought forward under glass, and planted out when about 

 to flower in a similar manner. For the summer months the following 

 flowers may be used : White. Iberis Tenoreana ; Alyssum calj^cinum ; 

 Ar'abis bellidifolia, and A. petrfe'a ; Actse^a racemosa ; Achillea Cla- 

 vennag ; White dwarf Campanula ; Valeriana montana ; Cardamine 

 asarifolia ; and Stevia Eupatoria. Blue. Campanula rotundifolia, C. 

 garganica, and C. pulla, Viola cucullata ; A'ster alplnus ; Lupinus 

 nanus ; Periwinkle ; Lobelia gracilis, L. cferulea, and L. unidentata ; 

 and the Calathian Violet. Yellow. Moneywort ; Lasthenia califoi-nica ; 

 Bartonia aurea ; yellow jMusk plant (MImulus moschatus) ; Hoop 

 Petticoat Narcissus ; and A'llium Moly. Ptirj^le. Wild Geraniums 

 of various kinds ; several kinds of Phlox ; dwarf Asters ; and dwarf 

 Stocks. Bed. Ly^chnis Isj'ta ; Pink-flowered Cistuses, and Helianthe- 

 mums ; Phlox Drummondii ; and several dwarf Pinks. This list is very 

 imperfect, but it will serve to give an idea of the kind of flowers which 

 are suitable. Heartseases may be added at pleasure, and many other 

 flowers will occur to every one fond of a garden. When an aquarium 

 is added to the rock-work, as in fig. 67, it will be necessary to place a 

 few aquatic plants in the water, and a few marsh plants round the borders 

 of the pond, for which purpose I have subjoined the following list of 

 suitable plants, some of which are quite hardy, and may remain in the 

 water all the year, and others will require protection during winter. 



List of Aquatic and Marsh Plants. 



Two of the handsomest a uatics I know are Ax>onogeton angustifblium, 

 and A. distacJiyon ; they have both white flowers tinged with pink, and 

 black anthers, which give them a very lively appearance. A. distacliyon 

 is much the larger plant of the two. They are both tolerably hardy, but 

 require protection during winter. Pontederia cordaia has arrow-shaped 

 erect leaves, and an upright spike of dark purple flowers. It is a native 

 of North America, and is quite hardy in England. Butomus tanbelldtus, 

 the flowering rush, with its head of pink flowers, and A' corns Calamus, 

 the sweet-scented water-reed, are tall showy plants, as is Cyperus Idngus, 

 which last bears some resemblance to the Papyrus of the Nile. For smaller 

 plants, may be mentioned the little Frog-bit, Eydrocharis morsus-rance, 

 with its pure white flowers ; Hottonia palustris, the water violet, with 

 its pretty pink flowers ; Cdlla palustris, the water dragon ; Cdltha 

 palHstris, the marsh marigold ; Nymphce'a alba, the common water-lily ; 

 Stratiotes aloules, the fresh-water soldier ; Sagittaria sagittifblia, the 

 Chinese arrow-head, with its white and green flowers ; Pinguicula lusi- 

 tdnica ; Sdmolus Valerdndi ; Villdrsia nympkceoides, the yellow fringed 

 buck -bean ; Comarum palustre; and Nuphar ddvena. The beautiful 

 little Polygonum ampldhium, the rose-coloured water-pepper, with its 

 dark pink flowers, of which there is so much in the large piece of water
