This article is about Anemonopsis. For the yerba mansa plant, see [Anemopsis](/source/Anemopsis).

***Anemonopsis***, the **false anemone**,[1] is a [monotypic](/source/Monotypic) [genus](/source/Genus) in the [family](/source/Family_(taxonomy)) [Ranunculaceae](/source/Ranunculaceae), containing only the species ***Anemonopsis macrophylla***, [endemic](/source/Endemic) to Japan's main island of [Honshu](/source/Honshu). The generic name *Anemonopsis* refers to it being *[Anemone](/source/Anemone)*-like (**[-opsis](https://en.wiktionary.org/wiki/-opsis)**), and its [specific epithet](/source/Botanical_name) *macrophylla* means "large-leaved".

## Description

*Anemonopsis* is a [herbaceous perennial](/source/Perennial_plant) growing approximately 75 cm high, with pale lavender flowers in late summer, each about 2 cm in diameter. The flowers are bowl-shaped with a rosette of petals in the center, and are downward facing. The flowers are held well above the foliage; although not a small plant, the overall impression is one of daintiness and airiness.

When in full bloom, the flowers resemble small [lotuses](/source/Nelumbo_nucifera), giving rise to its Japanese name of (蓮華升麻, *renge-shōma*, lit. "lotus-**[shōma](/source/Cimicifuga)**"). The genus *[Kirengeshoma](/source/Kirengeshoma)* in turn is named after it.

Native to Japan's colder [temperate](/source/Temperate) areas (southern [Tōhoku](/source/T%C5%8Dhoku) to [Kinki](/source/Kinki)), *Anemonopsis* is frost-hardy at least to [zone](/source/Hardiness_zone) 4. It is a true woodland plant and cannot tolerate full sun without the leaves scorching, except perhaps in very cool, damp climates. It must also be protected from drying winds.

## Cultivation

Like many other [herbaceous perennials](/source/Herbaceous_perennial) from Japan, *Anemonopsis* demands summer moisture, but resents excessively wet conditions in winter. It is thus much more easily grown in [continental climate](/source/Continental_climate) of the eastern United States and Canada than in the [Mediterranean climate](/source/Mediterranean_climate) of the [Pacific Northwest](/source/Pacific_Northwest).

## Propagation

*Anemonopsis* is self-fertile, and an isolated plant will set modest amounts of seed. If sown in containers as soon as ripe and the seed containers exposed to winter chilling, germination will occur the next spring. Unlike some members of the [Ranunculaceae](/source/Ranunculaceae), which are notorious for their seeds remaining viable only for a very short time, *Anemonopsis* seed retains its viability in storage to a reasonable degree. However, fresh seed is preferable to stored seed.

As with many other members of the [Ranunculaceae](/source/Ranunculaceae), seedlings of *Anemonopsis* form only [cotyledons](/source/Cotyledons) in their first season; the first true leaves form the year after [germination](/source/Germination). Seedlings are slow to reach maturity, and flower in about 5 years. They may be more easily handled by growing in pots until they reach a size suitable for planting out.

No particular treatment of seed is necessary other than exposure to ordinary winter chilling.

*Anemonopsis* can also be propagated by division.
