Eriocapitella hupehensis
Eriocapitella hupehensis, a species of flowering plant in the Ranunculaceae family of plants and has an extensive native distribution across a large area of Asia.[1] The plant was previously known as Anemone hupehensis and is often still referred to as such. Together with several closely related species and hybrids between these species, in horticulture these plants are often referred to as Japanese anemones.[2] The specific epithet hupehensis, which means "from Hupeh (Hupei, Hubei) province, China",[3] refers to a region where the species is known to occur. In Chinese, it is called dǎ pò wǎn huā huā (打破碗花花),[4] which means "broken bowl flower".[5] DescriptionEriocapitella hupehensis is a perennial herbaceous plant with a rhizome-like root structure. It is a clump-forming plant with 3–5 basal leaves, each with a petiole 5 to 35 cm (2 to 14 in) long. The leaf blades are ternate with a central leaflet 4 to 10 cm (1.6 to 3.9 in) long and 3 to 10 cm (1.2 to 3.9 in) wide. The lateral leaflets are similar to but smaller than the central leaflet. The stem is 30 to 100 cm (12 to 39 in) long, occasionally up to 120 cm (47 in) long. A whorl of 3 leaves (technically bracts) wraps around the stem. The stem leaves are similar in appearance to the basal leaves but somewhat smaller. The inflorescence is a cyme with 2 or 3 branches and a primary flower stalk 3 to 10 cm (1.2 to 3.9 in) long. Each flower is approximately 5 cm (2.0 in) across. In its native habitat, the flower usually has 5 sepals (no petals) but cultivated plants have double flowers with around 20 sepals. The sepals may be purple, purple-red, pink or white. In the center of the flower, there are more than 100 pistils each 1.5 mm long, surrounded by prominent yellow stamens approximately 5 mm (0.2 in) long. The fruits are small ovoid achenes with straight styles.[4] TaxonomyEriocapitella hupehensis was described by Maarten J. M. Christenhusz and James W. Byng in 2018.[6] Like other members of genus Eriocapitella, E. hupehensis was formerly a member of genus Anemone. The basionym Anemone japonica var. hupehensis Lemoine was described in 1908.[7] DistributionEriocapitella hupehensis is native to Asia, in the Eastern Himalaya region, East Asia, and Southeast Asia.[4]
The species was introduced into Czechoslovakia, Ecuador, and Germany.[1] EcologyEriocapitella hupehensis along with four other taxa (E. × hybrida, E. japonica, E. tomentosa, and E. vitifolia) are known as fall-blooming anemones.[8] In its native habitat, E. hupehensis flowers from July to October.[4] CultivationEriocapitella hupehensis and its cultivars are cultivated worldwide, especially in Asia, Europe, and South America, where naturalized populations are known to exist. In China, E. hupehensis has been cultivated since at least the 17th century, probably dating back to the Tang dynasty (618–907). Hundreds of years ago, a semi-double form of E. hupehensis escaped cultivation and spread across China to Japan and Korea. This descendant of E. hupehensis, now known as E. japonica, is a parent of the artificial hybrid E. × hybrida.[9][8][10] At the Chicago Botanic Garden, Rudy experimented with 26 cultivars of fall-blooming anemones over a 5-year period beginning in 1998. His experiments included three cultivars of E. hupehensis:[8]
As of March 2020[update], the following cultivars have gained the Award of Garden Merit (AGM) from the Royal Horticultural Society:[14]
