Ranunculus Lingua ‘Grandiflora’, commonly known as Giant Spearwort, is a bold and striking marginal pond plant prized for its large, glossy yellow buttercup-style flowers and strong upright growth. Flowering through the summer months, it adds vibrant colour and height to pond edges and damp garden areas.
This variety produces tall stems with narrow, spear-shaped green leaves, creating a natural, slightly wild look that blends beautifully into wildlife-friendly ponds. The bright blooms attract pollinators, making it a great choice for encouraging biodiversity.
Ideal for planting in shallow water or consistently moist soil, Giant Spearwort is easy to grow and thrives in sunny positions. Its robust nature makes it suitable for larger ponds or naturalistic settings where it has space to spread.
