Caltha palustris polypetala (Giant King Cup) – Marginal Pond Plant – UK Grown

Caltha palustris polypetala, commonly known as Giant King Cup, is a stunning marginal pond plant. It produces large, bright yellow flowers that bloom in spring, creating a striking contrast against lush green foliage. This plant is perfect for adding a splash of colour to your pond or water garden.

Giant King Cup thrives in damp, boggy soil or shallow water, making it ideal for pond edges. It prefers full sun but can tolerate light shade, growing best in slightly acidic to neutral soil. To ensure healthy growth, keep the plant’s roots consistently moist, especially during dry weather.

For planting, place Caltha palustris polypetala in an aquatic basket with loam-based compost. Position the basket so the crown stays just above the water level. If planting directly in damp soil, ensure the area remains moist throughout the growing season. Regular watering is key to maintaining its vibrant appearance.

As a UK-grown plant, Caltha palustris polypetala is perfectly suited to local conditions and climates. Our plants are nurtured to the highest standards for strong, healthy growth.
