Persicaria x cult. 'Johanniswolke'

Best planted in autumn or early spring.

Low maintenance. Can be cut back after the first flush of flowers to encourage new growth and a bushier habit, though its natural form is usually quite appealing.

Ideal for perennial borders, naturalistic plantings, cottage gardens, and as a filler or "mist" plant to soften bolder colors or coarser textures. Excellent for adding late-season interest.

Medium water requirement. Keep consistently moist, especially during dry periods.

Prefers moist, well-drained, humus-rich soil. Tolerates a wide range of soil types but performs best with consistent moisture.

Excellent (USDA Zones 4-8). Very cold-hardy.

Thrives in full sun to partial shade. Best flowering in ample sunlight.

Produces abundant, extremely fine, cloud-like sprays of tiny, pure white flowers on wiry, branching stems, creating a misty effect. Blooms profusely from July to October, often continuing until frost. Attracts beneficial insects.

Deciduous. Slender, lance-shaped, mid-green leaves.

Upright, slender, clump-forming perennial. Forms a loose, open mound, typically reaching 80-120 cm (31-47 inches) in height and 60-80 cm (24-31 inches) in spread.
