Edelweiss is known for growing in romantic and inaccessible crevices up in the Alps, but is also perfectly suitable for your own rockery or border! The silvery foliage gives rise to unique, 10cm blooms, like miniature, woolly starfish! It prefers a sharply drained, neutral or alkaline soil in sun.
Sow from March to May. Place seed on the surface of a good free draining seed compost mixed with some grit. Do not cover the seed. Seal container inside a polythene bag and place at 15-20C until after germination, which can take 1 to 2 months. Do not exclude light at any stage, as this helps germination. Transplant seedlings when large enough to handle into 7.5cm pots. Grow on in a cold frame or sheltered corner. When plants are well grown, plant out 1cm apart. The plants will be more silvery when grown in lighter, poorer soils. Avoid exposing the plants to excessive wet winter conditions.
