Some of the species are grown in gardens. Their popularity varies by species and region. In addition to certain straight species being available, hybrids and cultivars are available for certain species. Certain species, such as
Anemone coronaria, are typically only available in hybrid form while others, such as
Anemonoides blanda are nearly always sold in straight species form. Cultivated anemones are nearly always one of the following colors: bluish violet, white, pink, red, and hues in a range between violet and pink. There are no truly blue anemones, despite the frequent use of the label "blue" in marketing to describe blue-violet flowers (flowers that are more violet than blue). One species of anemone,
Anemone ranunculoides, is unusual for its yellow flowers. In horticultural terms there are three main groups: • spring-flowering species found in woodland and alpine meadows, often
tuberous or
rhizomatous; e.g.
Anemonoides nemorosa,
Anemonoides blanda • spring- and summer-flowering species from hot dry areas, with tuberous roots, e.g.
Anemone coronaria • summer- and autumn-flowering species with fibrous roots, which thrive in moist dappled shade; e.g.
Eriocapitella hupehensis The spring-flowering autumn-planted ephemeral species
Anemonoides blanda is grown in large-scale commercial cultivation and can be purchased in bulk quantities. It is most commonly-available with a bluish violet flower (usually erroneously called "Blue Shades" despite its flower being more purple than blue) that varies from intense to pale, depending upon the individual plant and possibly soil conditions. A white-flowered form is the second-most common type. The least common of the commonly-cultivated forms is a pale pink. The violet, and especially pink, forms sometimes possess petals that fade to white near the flower center. The genus contains quite a number of other spring-flowering species.
A. hortensis and the hybrid
A. fulgens have less-divided leaves than some others and have rose-purple or scarlet flowers. Among the most well-known anemones is
A. coronaria, often called the
poppy anemone. It is a tuberous-rooted plant with parsley-like divided leaves and large poppy-like blossoms on stalks of from 15–20 cm high. It can be planted in the fall in zones 7 or 8 without extra protection or in spring in cooler zones. If planted in fall it will flower in the spring and if planted in the spring it will flower in late summer. The flowers are typically scarlet, crimson, bluish purple, reddish purple, or white. There are also double-flowered varieties, in which the stamens in the centre are replaced by a tuft of narrow petals. It has been used as a garden plant, in hybrid form in particular, for a long time in some parts of the world. Double forms are named varieties.
A. coronaria has been described by some professional sources as preferring acidic soil and by others as preferring alkaline soil. Hardy species may be planted in October in many zones. Unlike a hardier species such as
A. blanda,
A. coronaria is described as hardy only as low as climate zone 7 by some sources and by others hardy only as low as zone 8. Various strategies, such as the use of protection, can be tried to plant them outdoors in fall in zone 6 but results may vary. As with other plants, some species can be readily raised from seed while some hybrids may be sterile.
A. blanda typically blooms in mid spring. The larger anemone species typically grow well in partial shade, or in full sun provided they are shielded from the hottest sun in southern areas. A well-drained soil, enriched with compost, is typically utilized. If cut flowers are desired, it is best to harvest the flowers early in the morning while it is still cold outside while the bloom is still closed. To open your flowers place in room temperature water out of direct sun.
A. coronaria blooms can be purchased from some florists, between November and June depending upon availability. ==Anemones in culture==
