If planning to grow Celmisia it is best to start them off indoors. The seeds of mountain daisies should be as fresh as possible as they are short lived. The seeds of mountain daisy should be sown on the surface at a temperature of 15 degrees celsius in the light and take anything from a month to six months to germinate. They should be grown until roots are fully established and then planted out in the middle of spring with a spacing dependent upon the species size: small (15 cm); medium (45 cm); spreading (1.5m). They like to grow in peaty acidic soils with good drainage in anything from partially shaded to sunny areas of the garden.
Celmisia should be protected from rain and snow, but be well watered, so water from below in the summer to prevent soil drying out. If you require more Celmisia plants then you can get more by taking cuttings or dividing mountain daisy plants at the beginning of summer.
