Caltha palustris (Marsh Marigold)

Also known as 'King Cup'.

Once established it produces a mass of bright yellow flowers very early in the spring, almost a ball of yellow.

After flowering in March and April most foliage will die back. Remove dead leaves to tidy and encourage a potential second flowering.

Plant in full sun to partial shade between 0cm and 15cm deep.

• Flowering period: March & April
