Baldellia ranunculoides, or Lesser Water-plantain, produces dainty, three-petalled flowers that range in colour from pale pink to lilac or occasionally white. The petals are rounded and overlap slightly, giving the flowers a delicate, buttercup-like appearance. Each flower is typically 1–2 cm across and borne in open, branched clusters (panicles) on slender, upright stalks. Blooming mainly from June to August, the flowers open in succession, often just a few at a time, and are insect-pollinated.
Fruit:
Following pollination, the flowers develop into small, dry fruits composed of numerous achenes—tiny, one-seeded segments that collectively form a rounded head. The fruiting heads ripen by late summer and are dispersed primarily by water movement. Though small and inconspicuous, the seeds play a key role in the plant’s colonisation of wetland habitats, especially in shallow, nutrient-poor waters.
Leaves:
The leaves of Lesser Water-plantain are variable in shape depending on whether they are submerged or emergent. Submerged leaves are often linear or strap-like, while emergent ones are broader, lanceolate to oval, and held on long stalks above the water or mud surface. All leaves are smooth-edged, soft-textured, and pale to mid-green in colour. The rosette-forming habit and narrow flowering stems help distinguish it from similar aquatic species such as Alisma plantago-aquatica.
Fragrance:
The flowers of Lesser Water-plantain do not emit any noticeable fragrance. Their primary appeal lies in their soft coloration and delicate form, rather than scent. While they do not play a significant olfactory role in their habitat, the flowers still attract small pollinators through visual cues and subtle nectar rewards, contributing to the overall biodiversity of wetland ecosystems.
Frequency (UK):
Occasionally seen
