Description
Ranunculus flammula, commonly known as Lesser Spearwort, is a charming marginal pond plant that produces small bright yellow buttercup-like flowers throughout the summer months. The cheerful blooms appear above slender stems and narrow green leaves, adding a splash of colour to pond edges and damp garden areas.
This hardy aquatic plant thrives in shallow water or moist soil, making it ideal for planting in pond margins, wildlife ponds, streams, and bog gardens. Its natural growth habit helps soften the edges of ponds while creating a more natural, wildlife-friendly environment.
Ranunculus flammula is particularly valuable for wildlife ponds, as the flowers attract bees and other pollinating insects, helping to support biodiversity around the water.
