Cult. These plants succeed best in a light sandy soil, in moist 
shady situations. They may be either increased by dividing the 
roots, or by seeds. The D. bulbifera may be encreased by the 
bulbs which grow in the axillee of the leaves. They are all or- 
namental plants, and deserve to be cultivated.

Cult. The species of this genus are well adapted for orna- 
menting rock-work, but as they are very rare and apt to be killed 
in the winter, we therefore would recommend a plant or two of 
each to be planted in pots, and placed among other alpine plants. 
A mixture of sand, loam, and peat will answer them well; the 
pots which they are planted in should be well drained with 
potsherds. They may be increased by dividing the plants at the 
root, but more readily by seeds or by young cuttings.
