Cult. These are pretty little creeping plants, generally 
having the leaves silvery on the under sides. D. rèpens, Caro- 
liniàna and rotundifolia grow well in the seams between flat 
stones in front of a stove or green-house ; and even the other 
species will do in a similar way through the summer. All grow 
well in pots in a mixture of peat, loam, and sand; and are 
easily increased by dividing the plants, which are all creepers.
