This is a neat, and very desirable sweet-scented little 
hardy alpine perennial, which grows freely in a soil composed 
of sandy loam and leaf-mould. It attains a height of six 
inches, flowers from March to May, and sometimes a second 
time during the growing season. 
It requires to be planted in rather a shady situation, and 
to be freely supplied with moisture during the growing 
season ; but like all other perennials, it must have its season 
of repose, and should be kept rather dry when dormant, 
otherwise the large bulb-like crowns become much injured 
from damp, and freguently perish during the winter. 
It is easily increased by the small runners, which are 
produced freely when the plant is in a growing state, or from 
seeds.
