The chief enemy of this little plant, and indeed of all alpine plants with silky or cottony foliage, is moisture in winter, which soon causes it to damp off.
Although somewhat apt to damp off on level ground, it is a perennial on raised ground, and keeps up a succession of bloom.
Cuttings inserted in August root freely, and may be wintered in the greenhouse if kept fairly dry, otherwise they will damp off.
