Description

Plant Type: Perennial herbaceous plant.

Height: Typically grows between 30 to 60 cm (12 to 24 inches).

Flowers: Bright orange or yellow globe-shaped flowers, 3-5 cm in diameter, with numerous overlapping petals forming a rounded shape. Each flower has a delicate, airy appearance, with stamens prominently displayed in the center.

Leaves: Basal leaves are deeply lobed and palmately divided, dark green, and glossy.

Stem: Erect, unbranched stems that support the solitary flowers.

Blooming Season: Late spring to early summer (May to July).

Known Range

Native Range: Native to parts of East Asia, primarily found in China (Northeastern China, Inner Mongolia), extending into Russia (Far East), Mongolia, and Japan.

Naturalized Range: Has been cultivated and naturalized in some parts of Europe and North America.

Preferred Habitat: Thrives in moist meadows, along streams, and in alpine regions at altitudes ranging from 500 to 2500 meters.

Care Requirements

• Sunlight: Prefers full sun to partial shade. In warmer climates, partial shade is beneficial to prevent scorching.
• Soil: Requires well-drained, fertile soil with high organic content. The soil should remain consistently moist but not waterlogged.
• Watering: Regular watering is essential, particularly during dry periods. Avoid letting the soil dry out completely.
• Temperature: Hardy in USDA Zones 4-7. Can tolerate cold winters but may struggle in regions with excessively hot summers.
• Fertilization: Apply a balanced, slow-release fertilizer in early spring to encourage healthy growth and abundant flowering.
• Propagation: Propagated by division in early spring or by seeds sown in autumn. Division is the most reliable method.
• Pruning: Deadhead spent flowers to encourage continuous blooming and prevent self-seeding. Cut back the foliage after the plant has finished flowering.

Additional Notes

Companion Planting: Pairs well with other moisture-loving perennials like astilbes, ferns, and hostas, making it an excellent choice for bog gardens and water edges.

Pests/Diseases: Generally pest-resistant but may be susceptible to powdery mildew in humid conditions. Good air circulation can help prevent this issue.
