Ranunculus flammula, commonly known as lesser spearwort, is a low-growing, spreading perennial with narrow, dark green leaves forming dense mats along wet soils and pond margins. In summer it produces small, bright yellow, star-shaped flowers held just above the foliage, creating a subtle yet attractive display in damp habitats. This species thrives in consistently moist or shallowly wet soil and provides ecological value by supporting pollinators such as bees and small insects. Its spreading habit and tolerance of wet conditions make it ideal for pond edges, bog gardens, and naturalistic or wildlife-focused planting schemes.
