Ranunculus flammula

Lesser Spearwort - Hardy plant

Ranunculus flammula
A pretty marsh plant, great in shallow waters and small ponds!
Lesser Spearwort likes boggy meadowland, riverbanks and marshlands. Also great in your little miniature pond. It has lovely little lemony yellow flowers and narrow foliage that initially grow in a rosette. The stems can turn red in sufficient, full sun - even more decorative! Lesser spearwort (Ranunculus flammula) actually tastes quite spicy, which accounts for the Latina 'flammula'.
Ranunculus is classified under Ranunculaceae.
This is a pond edge plant suitable for shallow waters up to 15 cm deep.

Lesser Spearwort or banewort (Ranunculus flammula) is an aquatic best planted in a pond basket. Line the basket with jute and use a special pond medieum. Plant your lesser spearwort in the basket and fill up with more pond medium. Cover around the plant with the jute hanging over, then finish off with a layer of grit or pebbles. Place the basket just below the surface of the pond, or at a maximum 15 cm deep. If you don't have a shallow edge to your pond, stand the basket on bricks piled to the right depth. Full sun or part shade. Best time to plant is May-June.

Lesser Spearwort (Ranunculus flammula) with other plants

The lovely and conspicuous little yellow flowers on lesser spearwort (Ranunculus flammula) will really stand out at the edge of your pond. The aquatic mixes well with other yellow flowers like the Marsh Marigold (Caltha palustris) and Creeping Jenny/Moneywort (Lysimachia nummularia) but also with plants that have yellow variegated foliage like Culumus/Sweet Flag (Acorus gramineus) 'Ogon'.


Ranunculus flammula (lesser spearwort) is a strong marsh plant that will actually grow anywhere. Lesser spearwort does however like a nice sunny spot. Cut back dead foliage in the autumn and be sure to remove it from the pond. If your clump of lesser spearwort becomes too large, just remove it from the pond in May and divide the clump into smaller pieces. Replant only one or two good pieces.

Lesser Spearwort in the winter

Lesser Spearwort (Ranunculus flammula) will die back above ground in winter. As long as the roots are under water or soil, it will manage perfectly well. Horizontal stems can root from the leaf nodes and stems, enabling it to multiply and spread. Cut back all the previous years dead foliage in early spring and the plant will soon shoot up and treat you to new flowers in the summer.


Wild lesser spearwort (Ranunculus flammula) originated in wet places such as shores, shallow waters and also boggy meadows in cooler climes in the Northern hemisphere. It has beautiful lemony yellow flowers and narrow leaves that start off in a rosette. Horizontal stems can root from the leaf nodes and stems, enabling it to multiply and spread. Lesser spearwort (Ranunculus flammula) is also called banewort and has an unusually spicy flavour (accounting for the Latin flammula).
Ranunculus is classified under Ranunculaceae.
