Anemone
Family: Ranunculaceae
Of the 120 species in this genus, quite a wide range is grown in American gardens. Many are native to Europe and western Asia, but there are species native to japan, the Americas and most areas of the northern temperate zone. This genus contains herbaceous perennials as well as tuberous types.
Species
Best known to gardeners is probably the spring-flowering A. coronaria, zone 8. It is also widely grown for the cut flower market. Flower colours include white, red, pink, blue and purple. The most popular strains are the De Caen Group with single flowers, and St Brigid Group with double flowers. The woodland anemones, A. blanda and A. nemorosa, grow in cooler zones, often becoming naturalized under trees which suits their woodland origin. They are also spring flowering. The Japanese windflower, A. hupehensis, is a tall-growing perennial, often reaching more than 1 m (3 ft) in height. This flowers in autumn, with single- or double-flowered forms in white, pink and lavender pink. Although deemed to be invasive by some growers, it is easily controlled. Numerous other species are grown in American gardens. and are worth looking out for.
Cultivation
Spring-flowering anemones should be planted out in late summer to early autumn, the tuberous types with their pointed ends down. Plant where they are to grow as they do not transplant well. Woodland anemones will grow in shade, but A. coronaria should be given plenty of sun and shelter from wind.
A. hupehensis prefers partial shade and shelter from strong winds. It can he transplanted in late winter or early spring. All anemones prefer well-drained soil containing plenty of organic matter. Overly wet or poorly drained soil will rot the roots or tubers. Once vigorous growth is established, water regularly and apply fertilizer as the buds begin to form.
Climate
Anemones can be grown in zones 5 to 8.
