270 ALPINES AND BOG-PLANTS 



Ranunculus aconitif alius, Anemone 7-ivularis, Thalictrum 

 aquilegifolium. Lychnis haageana. Spiraea japonica, with 

 its fellows, and Mimulus Model and Mimulus Brilliant — 

 which are also magnificent on the inner edge, pushing 

 masses of rose and vermilion right out over the water — 

 and, of course, besides the larger Primulas, pulveruknta, 

 japonica, and siklcimensis, the invaluable, gorgeous Myo- 

 sotis pahistris, which, like the Mimulus, is no less beautiful 

 and effective for the very water"'s edge itself. 



If, too, you plant Potentilla Comarum and Menyanihes 

 trifoliata on the rim of the pond, they will both spread 

 and ramp forwards across the face of the ripples. Calla 

 palustris, on the other hand, is, I think, happiest when 

 within root grip of wet fat mud. The Potentilla and the 

 Menyanihes thrive quite happily, emitting tufted silky 

 roots into the water, but the bog- Arum prefers the help 

 of a little soil, making mats of heart-shaped leaves across 

 the wet marsh, and sending up all along its branches the 

 white flowers, miniatures of Calla ethiopica. Orontium 

 aquaticum, another Aroid, with yellow spathe, loves 

 shallow water, but, for my own part, I have never 

 admired its colour, its shape, or anything about it, and 

 therefore have never made any prolonged effort to grow 

 it. Hottonia palustris is a dainty native, for quite shallow 

 depths, filling a whole pool with white fibres and masses 

 of the finest lacy foliage, from which shoot up above the 

 depths, whorled spikes of very large flowers of a very pale 

 rose-violet. With this I have never had much to do. 

 My efforts to establish it did not prosper, and, so heartily 

 does it grow when the will takes it, that I do not alto- 

 gether regret the fact that, in my case, the will was 

 lacking. 



Of course, if you want a very full collection of water- 

 plants, you will not only build one false wall, giving you 

 a marshy edging to your pond, but also, within that
