Seeds of edelweiss should be sown about February 1, which gives plants large enough to plant out in permanent quarters about May 1. If planted in good well-drained ground, the plants are sure to make a good growth so that by the middle of September there will be an occasional flower. However, it is not until the following year that one gets a full crop of flowers, so many in fact that it seems to exhaust the plants, which should now receive a good deal of care. Old plants divided early in the fall and wintered in coldframes give very good results, or late-sown seedlings carried over winter in the same way do well.

To establish a colony of edelweiss an English writer (Gn. 52, p. 146) advises that a few stray seedlings be firmly planted in a narrow chink of rock so placed that a deep fissure of gritty or sandy loam may be assured for the roots to ramble in. Plants in pots may be grown and flowered when the collar is tightly wedged between some pieces of stone or old mortar. The plant is best propagated by seeds, as division is not always successful.
