AQUATIC ADJUNCTS OF A ROCK GARDEN. 115 



than the Water Hawthorn, for it spreads over the 

 water in a graceful sheet and is pleasantly perfumed. 

 Most of the plants named will be comfortable in a 

 pool a foot to eighteen inches deep. The Nymphaeas 

 may have two to two-and-a-half feet of water. 



If a pond already exists in the garden there cannot 

 be a better plan of beautifying it than to throw weighted 

 roots of hardy Nymphaeas into the water a few feet 

 from the edge, and leave them to establish themselves 

 and spread. Other things can be planted near the 

 margin, such as Willow Herbs (Epilobiums), Japanese 

 Irises (Iris laevigata or Kaempferi), and smaller 

 things such as Marsh Trefoil, Bog Bean (Parnassia 

 palustris) and Water Forget-me-not. These will 

 thoroughly enjoy having their toes in the water. 

 Two beautiful dwarf things which can be grown 

 quite near are the charming hardy Primroses, Primula 

 rosea and P. japonica. The former is a very low- 

 growing plant, the latter grows to fifteen or eighteen 

 inches high. A healthy colony of the Japanese 

 Primrose, carrying its blooms in tiers or whorls in 

 June, is a sight not easily forgotten. Both of these 

 delightful plants can be grown from seed quite readily. 



As an example of how a small piece of marshy ground 

 can be made beautiful with water plants I would 

 mention the little pond which the visitor to Kew 

 Gardens may find who, having passed through the 

 Rhododendron dell, turns his steps towards the 

 pagoda at the Richmond end of the gardens. Once 

 upon a time this was no more than a weedy bog : it 

 is now an exquisite little picture of flower and water
