Butomus umbellatus ‘Schneeweisschen’ – White Flowering Rush

A refined, elegant marginal plant for ponds and water gardens

Product Description

Enhance your pond margins with Butomus umbellatus ‘Schneeweisschen’, a beautifully delicate white‑flowered form of the classic Flowering Rush. This graceful aquatic perennial produces pure white, star‑shaped blooms held above light green, slender stems, offering a softer, more refined look than the traditional pink variety.

Perfect for wildlife ponds, naturalistic schemes, and contemporary water gardens, ‘Schneeweisschen’ thrives in consistently moist conditions and brings height, movement, and seasonal interest from late spring through summer. Its clean, architectural form makes it ideal for softening pond edges while maintaining a calm, elegant aesthetic.

Key Features

• Pure white flowers from June to August for a fresh, airy display
• Light green stems create a softer, more delicate appearance
• Excellent for marginal shelves, pond edges, and damp ground
• Hardy, vigorous, and easy to grow
• Adds vertical structure and texture to aquatic planting
• Supports pollinators and enhances pond biodiversity
