Mountain windflower, Greek windflower, Winter windflower, Sapphire anemone
Anemone blanda (Mountain windflower). This is a delicate-looking very early-blooming, hardy tuber. It brings lovely daisy-like flowers to the early spring landscape and lacy fern-like foliage which covers the ground with an airy delicacy. An excellent companion for all other spring bulbs, tulips and daffodils in particular, this Anemone provides low and spreading cover for the bulb bed. 'Blue Star' and 'White Splendor' are recommended cultivars.
Plant at a depth of approximately 6cm. They prefer a rich, well drained soil and a sunny, protected site. Some dappled shade is alright. Prefers moist conditions.
Border, naturaliser, ground cover, walls, rock garden.
