Edelweiss Leontopodium Alpinum is a famous, short-lived, herbaceous perennial native to alpine areas of Europe. Edelweiss seeds can be sown indoors 4-6 weeks before the last frost, so seedlings can be transplanted outdoors after the last frost. So-called Edelweiss of the Alps is a clamping, woolly perennial wildflower with highly attractive gray-green foliage and small yellow flowers that seat on a top of showy, fluffy, white-woolly, bract-like leaves, and this highly attractive combination is shaped like a lion’s paw. Edelweiss starts to bloom in the summer. The established Edelweiss likes to grow in full sun, and cool summer climates are preferable environments.
