THE NEW WATER-GARDENING 239 



garden is, indeed, scarcely less attractive than the pool 

 itself, and, given sufficient space, it might be extended 

 to include larger plants. None are more effective than 

 the Japanese Irises where they bloom, but unfortunately 

 they are apt to be flowerless. One finds that in the 

 beautiful gardens of the Scottish highlands, whither 

 travellers resort from all parts of the world to admire 

 the glorious hill and lake scenery, Iris laevigata varieties 

 are very shy, and often refuse to bloom altogether. There 

 are, however, other good Irises that will thrive and flower, 

 such as aurea, Monnieri, Pseudacorus (the common 

 yellow Water-flag) and orientalis. 



The Willow Herbs (Epilobiums) , though coarse, may 

 be remembered for distant colour on large sheets of 

 water. The splendid Senecio Clivorum likes a moist 

 spot, and so does S. Japonicus. With shade the stately 

 Lilium giganteum, the tallest and most imposing of all 

 Lilies, will thrive, and so will the hardy Ladies' Slippers. 

 The Panther Lily will thrive in sunshine if its roots are 

 in a cool, moist spot, and the same may be said of Astilbe 

 rivularis, A. Davidii, Montbretias Gerbe d'Or, Prometheus, 

 George Davison, Germania and Pluie d'Or all beautiful 

 varieties of different colours Caltha polypetala the 

 latter a better plant than the old Marsh Marigold and 

 Lobelia cardinalis. As a choice subject for a shady spot 

 in moist soil Ourisia coccinea may be named. It is a 

 lovely and uncommon little plant, only growing a few 

 inches high. It likes peaty soil, as indeed do all the 

 moisture-loving plants for the waterside. Another 

 interesting plant loving similar conditions is Pinguicula 

 grandiflora, the leaves of which catch small insects. The 

 advanced water-gardener will perhaps form a colony of 

 Sarracenia purpurea, a North American Pitcher Plant 

 which enjoys moist peat,
