The Anemone raddeana, often known as the Radde’s Anemone, is a perennial herbaceous plant from the Anemone genus of the Ranunculaceae family. The plant’s rhizome is horizontal or obliquely oriented, slender, and jointed. It has scale-like leaves, with singular basal leaves that are trifoliate.

The leaf stalks are either hairless or have sparse long soft hairs. The central leaflets are ovate or elliptical with sparse serrations along the edges. Its flower stem is nearly hairless, bearing a single flower.

The involucral bracts are segmented and diamond-shaped with five angles. Flower stalks either have sparse soft hairs or are nearly hairless. Its sepals are white, sometimes with a faint purple hue, elongated-circular, and hairless. The achene is narrowly ovate with fine hairs.

The flowering period is from April to May, with the fruiting period from May to June. In contrast to other Anemone species, the Radde’s Anemone has a multiplied number of sepals, giving it a double-petaled appearance, hence its name.

Anemone raddeana

The Radde’s Anemone is found in China’s provinces of Liaoning, Jilin, Heilongjiang, and northeastern Shandong. It’s also found in North Korea and the Far East of Russia. It primarily grows in mountain forests and shady grasslands at elevations around 800 meters.

The Radde’s Anemone is cold-resistant, heat-sensitive, and prefers fertile soil. It propagates through seeds or rhizomes.

The rhizome of the Radde’s Anemone is used medicinally. It has a pungent taste, warm properties, and is toxic. It is traditionally used to dispel wind-dampness, dispel cold, relieve pain, and reduce swelling and abscesses.

Modern pharmacological research also indicates its potential in anti-tumor, anti-inflammatory, analgesic, and sedative effects.

Morphological Characteristics

Anemone raddeana

The Radde’s Anemone is a perennial herb that grows 10-30 cm tall. Its slender, jointed rhizome grows horizontally or obliquely, measuring 2-3 cm in length and 3-7 mm in diameter. The plant has scale-like leaves and singular basal trifoliate leaves with stalks measuring 5-15 cm.

The leaves are tri-lobed, and each lobe has a slender stalk, with two or three deep slits and is hairless. The leaf stalk is 2-7.8 cm long, either hairless or sparsely covered with long soft hairs. The flower stem is nearly hairless with 3 bracts, each with a stalk measuring 2-5 mm.

The leaflets are fan-shaped, 1-2 cm long, tri-lobed with the central leaflet being ovate or elliptical and the edges having sparse teeth.

The flower stem, nearly hairless, bears a single flower. The flower stalk is 1-1.3 cm long, either sparsely covered with soft hairs or nearly hairless. The involucral bracts are diamond-shaped with five angles.

There are 9-15 sepals, white or faintly purple, elongated-circular, measuring 1.2-1.9 cm in length and 2.2-6 mm in width, with a rounded or blunt tip, and hairless. The stamens measure 4-8 mm, with elliptical anthers approximately 0.6 mm long and rounded tips.

The filaments are thread-like, with about 30 carpels, the ovary densely covered with short soft hairs and a short style.

The achene is narrowly ovate with fine hairs. Inside, there are 20-30 seeds, crescent-shaped, velvety, with a tail wing at one end, and a semi-transparent endosperm. The thousand-seed weight is 1.5-2.0 grams. The flowering period is from April to May, and the fruiting period is from May to June.

Growth Environment

The Radde’s Anemone predominantly grows in mountain forests and shady grasslands at elevations around 800 meters.

Distribution Range

The Radde’s Anemone is found in China, as well as in North Korea and the Far East of Russia.

Growth Habits

The Radde’s Anemone thrives in cool, moist environments with ample sunlight. It’s cold-resistant but avoids high temperatures and excessive humidity. It prefers moist, well-draining, fertile loamy soil.

Propagation Methods

The Radde’s Anemone propagates through seeds or rhizomes.

Rhizome Propagation

A significant distinction between the Radde’s Anemone and other plants is its early growth as temperatures rise, even before the frozen soil has fully thawed. Its mature growth phase is from mid-April to mid-May, followed by a dormant period from mid-May to mid-July when the above-ground parts wither.

From mid-July to late September, it undergoes a physiological growth phase. Mature plants have 3-6 growth points on each rhizome, producing 3-6 small offshoots. Therefore, asexual reproduction (rhizome propagation) is primarily used in Radde’s Anemone cultivation.

The rhizomes, dug up in late May, are sorted based on color to determine maturity. The darker, deep red ones are processed for medicinal use, while the lighter red ones are used for planting.

The amount used for wild cultivation depends on the existing density of the Radde’s Anemone in the forest, while complete manual cultivation requires 200-250 kg of fresh rhizomes per acre.

Seed Propagation

Currently, the primary propagation of the Radde’s Anemone is through rhizomes, and generally, rhizomes that are two years or older can flower and bear fruit.

Seeds mature quickly and tend to fall off, and the timing of flowering and fruiting varies, making centralized collection challenging.

The Radde’s Anemone typically starts flowering in late April, with seeds maturing by the end of May. When 80% of the seeds reach maturity, the achenes are harvested.

These are then shade-dried, separated, sieved, packaged, and stored under low temperatures of 0-5°C. Seed cultivation involves immediate sowing upon collection, either in the fall or spring.

Cultivation Techniques

Site Selection and Preparation

The Radde’s Anemone thrives in natural forests in hilly and semi-mountainous regions. It’s ideal to choose broad-leaved forest land with loose, moist, and fertile humus or sandy loam soil. The slope shouldn’t exceed 15°, and flat forest lands are suitable.

The forest canopy should provide around 50% shade. It’s also feasible to select forest lands already inhabited by Radde’s Anemone, ensuring the ground remains moist with good drainage.

Small shrubs and weeds should be cleared, and beds prepared along the slope, 20cm deep and 1.5m wide. After land preparation, planting takes place from early May to mid-June.

Planting Methods

Two main methods are employed: horizontal bed trench sowing and broadcasting.

For horizontal bed trench sowing: Trenches 5cm deep and 10cm wide are dug horizontally. Rhizomes are then placed 8-10cm apart in rows, with a spacing of 1.0-1.5cm between plants in staggered double rows at the bottom of the trench. The trench is then covered with 3-4cm of soil, which is lightly compacted.

For broadcasting: The rhizomes are spread evenly over the bed, then soil from between the beds is used to cover them with a 3-4cm layer, which is again lightly compacted.

If conditions allow, a 2-3cm layer of compost should be applied over the bed. This helps reduce soil temperature, maintains moisture, facilitates rhizome dormancy in summer, and provides winter cold protection.

Rain and snow, in turn, help the nutrients from the compost to reach the Radde’s Anemone roots.

Interforest Management

Field management needs to be intensified to ensure optimal planting density. Weeds and shrubs should be timely removed during the growth phase to encourage robust growth and reduce the occurrence of pests and diseases.

Fertilization should be appropriate: apply mature organic fertilizer every 1-2 years and add a certain amount of phosphorus and potassium fertilizer. For every application, use 1000kg organic fertilizer and 15-20kg phosphorus-potassium fertilizer per acre.

Foliar fertilizers can be applied based on growth conditions. Irrigation should be timely: water during droughts and drain during heavy rains to prevent waterlogging and root diseases.

Timely Harvest

Radde’s Anemone enters its rapid growth phase between its 2nd and 4th year of cultivation. After 5 years, the rhizomes degenerate and gradually rot.

Growth starts in early April, dormancy begins in late May or early June, and by late August, underground rhizomes grow and produce roots. This period marks the best time for material accumulation in the rhizomes.

Pest and Disease Control

The Radde’s Anemone is highly resilient and usually doesn’t suffer from severe pests or diseases in its natural habitat. Minor occurrences of black spot disease, blight, and gray mold have been observed.

Caution is advised when applying pesticides, avoiding excessive concentrations and adhering strictly to recommended mixtures.

It’s crucial to apply treatments early and appropriately, alternating products and reapplying after rain. Physical pest control methods should be preferred to reduce chemical residues.
