 where it can do no harm. A decidedly pretty flower.

A trailing evergreen plant. It requires a shady position in moist, 

 sandy peat. It forms long, rather straggling stems, on which are 

 borne graceful, pale pink flowers in the summer. A pretty plant, 

 which looks well falling over the face of some rock. 



L. canadensis. — Is a larger form of the above ; more brilliant in

 soil, but thrives everywhere. It is altogether a more desirable 

 plant.
