Description
Anemone – Windflower
There are about 120 species of variable perennials and annuals from a wide range of habitats in temperate regions in the southern hemisphere, but most derive from the Northern hemisphere especially Asia, in this genus. These rhizomatous fleshly or fibrous rootstock bear ground-hugging plants divided into three main groups:
–Spring flowering species with tubers or rhizomes which are found in woodland and alpine pastures that can be divided in summer when dormant
–Spring or early summer flowering tuberous perennial thriving in hot dry summers like the Mediterranean and Central Asia and can be divided in summer when leaves have died down
–Late summer to autumn flowering herbaceous species with fibrous roots occurring in moist open woodland and grassy sites and can be divided in early spring or autumn.
Most bear both basal and stem leaves. The basal tuft leaves are rounded to oval 3-7 palmate or palmately lobed, with mid to dark green leaflets and lobes are often shallowly to deeply dissected or toothed and can be hairless or hairy. Smaller stalkless or short stalked stem leaves are often produced in groups of three or more arising from a single point beneath the flowers.
They bear starry or bowl or saucer shape flowers each with a central boss of stamens borne in cymes or umbels on branched or un-branched stems.
Cultivating Anemones have varying requirements: Grow in moist but well drained humus rich soil in sun or partial shade although drier conditions are tolerated when dormant in summer, but thrives in moist shaded position.
Given the right conditions and left undisturbed it will form wonderful carpets and some species can become invasive. Contact with sap may irritate skin
Prone to Synchytrium leaf galls, downy mildew, leaf and stem smut, Septoria leaf spot, powdery mildew, rust, nematodes, caterpillars, slugs and flea beetles.
Anemone nemorosa ‘Allenii’ – Wood Anemone – This vigorous low growing creeping perennial grows 3-6” tall and 12” or more wide. It produces slender brown rhizomes and rounded 3 palmate mid green basal and stem leaves 2-5” long with the narrow leaflets further lobed and toothed. In early spring it bears solitary deep lavender-blue flowers 1 1/2” wide with 6-8 outer tepals being shaded paler blue. The foliage dies soon after flowering.
