What does Edelweiss look like?
Edelweiss is a small, low-growing perennial reaching 8–20cm. The flowers are unusual — what appear to be white petals are actually woolly white bracts (modified leaves) surrounding small yellow flowers at the centre. The entire plant is covered in dense white hairs that protect it from UV radiation, cold winds and frost at high altitude. The overall effect is of a small, star-shaped, furry white flower with a distinctive felt-like texture that makes it immediately recognisable.
Edelweiss in Austrian culture
Edelweiss has appeared on the Austrian euro coins since 2002 and previously appeared on Austrian schilling coins. It is the symbol of Alpine military units across Austria, Germany and Switzerland. In the 19th century, giving Edelweiss to a woman was a proof of bravery and devotion — men would risk their lives climbing dangerous Alpine rockfaces to collect it. The flower was so heavily collected that it became legally protected in Austria, Switzerland and many other Alpine countries. The Sound of Music's "Edelweiss" song (1959) made it globally famous, though it was written by Rodgers and Hammerstein and is American in origin.
Growing Edelweiss in the UK
Edelweiss can be grown in UK gardens, though it requires specific conditions to thrive. It needs very sharp drainage — in UK conditions the main risk is winter wet rather than cold, since it tolerates hard frosts easily. Grow in a rock garden, alpine trough or raised bed filled with very gritty, low-fertility, alkaline compost. Full sun is essential. Good air circulation helps prevent the fungal issues that wet UK winters can cause. Edelweiss is available as seed (germinates readily after cold stratification) or small plants from alpine plant nurseries. It won't grow to the same bold clumps as in its native Alps but produces flowers reliably in a well-drained spot.
Other Alpine flowers worth growing
If Edelweiss inspires you to explore Alpine plants, many of the flowers that grow alongside it in the Austrian Alps also perform well in UK rock gardens. Gentiana acaulis (Trumpet Gentian, intense blue) flowers in spring; Saxifraga species form tight cushions covered in white or pink flowers; Pulsatilla vulgaris (Pasque Flower) is a British native Alpine meadow plant with stunning purple flowers in April. All need the same sharp drainage and full sun as Edelweiss.
