Edelweiss is a favourite wildflower of the Swiss Alps, best suited to growing in a well-drained rock garden, scree or alpine trough. Plants form a low clump of silvery grey foliage, bearing odd clusters of woolly white flowers in early summer. These can be cut, or even dried. Short-lived in gardens, these will sometimes self seed when happy. Best in regions with cool summers. Drought-tolerant once established.
