PLANTS FOR THE WATERSIDE 81 



three feet in diameter. Will grow in sunshine or shade 

 in any soil by the waterside. 



Polygonum, — P. cuspidatum and P. sachalinense, men- 

 tioned among " large-growing plants " are well suited 

 for positions in the vicinity of water. 



Primula japonica. — A very handsome member of the 

 Primrose family, growing, in a damp spot, to a height of 

 three or four feet. The type bears flowers of a deep 

 rose-crimson, and there are varieties with pink and rose- 

 eyed, white flowers. A beautiful picture is obtained by 

 planting the type by the hundred on the margin of a 

 pond or lake almost level with the water, as when the 

 plants are in full flower their rich colouring is reflected 

 on the placid surface. Primula japonica will grow with 

 the water level with its crown, and does well under 

 deciduous trees such as Limes. Primula rosea, with 

 deep rose-carmine flowers, only grows to a height of 

 nine inches. It likes a moist situation, but should 

 occupy an open space where it will not be overcrowded 

 by stronger-growing subjects. 



Rodgersia podophylla. — A very handsome-leaved plant 

 producing in the summer a tall branching flower-spike 

 of ivory-white blossoms. Its foliage is, however, its 

 greatest attraction, this being over a foot in diameter, 

 and divided into five deeply-cut lobes. The leaves are 

 bronze in colour, and therefore very effective. It does 

 well in a porous soil of leaf-mould or peat at the water's 

 margin. 



Saxifraga peltata. — A robust plant growing well in 

 porous soil by the waterside. In the spring it throws 

 up from its leafless crown tall flower-spikes sometimes 

 three feet in height, bearing loose clusters of pale pink 

 flowers six inches in diameter, the individual blossoms 

 of which are half an inch across. Later on the large, 

 handsome leaves are produced, a foot in diameter, 

 borne on stalks eighteen inches in length.
