How to Grow Edelweiss (Leontopodium Plants)

If growing outdoors from seed then sow the Edelweiss seeds on the surface.

This should be done in the spring before the last frost.

Edelweiss prefers to grow in a partly shaded part of the rock garden, in a gritty loose soil that is close to neutral acidity (pH 6.5 to 7.5).

If you plan to first grow Edelweiss indoors, then the process should start about two months before they are due to be transplanted into the garden (following the last frost of spring).

The seeds should initially be imbibed by placing the seeds (within soil) in a black plastic bag, then putting them in the fridge for three weeks.

Seeds should then be sown out at a temperature of 12 Celsius (54°F). Edelweiss plants will normally take about two to six weeks to germinate.

Once established they should be spaced out at from 10 cm (4 inches) apart for small Leontopodium species, to 30 cm (12 inches) apart for larger Leontopodium varieties.

Caring for Edelweiss Care

Leontopodium Care: Edelweiss like to grow in snow, and thus take a little looking after in areas that do not receive snow.

If this is the case you should surround the Edelweiss plant with a mulch in the winter to simulate the snow experience. This mulch should be removed at the start of spring.

If you live in a snowy area, then leave Edelweiss be in the winter, but protect it from heavy rainfalls in both circumstances.

Further plants can be propagated by division, this should be done every couple of years due to the short life span of Edelweiss.
