Description of Ranunculus flammula (Lesser Spearwort)

Ranunculus flammula is lesser spearwort, a UK native buttercup for wet ground and shallow margins. It’s a simple plant that looks right in natural pond edges and bog gardens, and it flowers for a long time in summer.

Appearance

It has narrow, slightly fleshy leaves and low, creeping stems. Small yellow buttercup flowers appear through the warmer months. It stays low, often 10 to 30cm, and can form a loose carpet in wet mud.

Care Guide

It’s easy, but it appreciates light and open space. Dense shade makes it thin out.

  • Sun: Sun to part shade.
  • Soil: Wet soil, mud, or aquatic compost.
  • Water: Boggy ground to very shallow water.
  • Control: Lift and thin if it spreads into baskets of slower plants.
  • Tidy up: Trim after flowering if it looks messy.

If you want it to look more deliberate, plant it in a small basket and let it trail over the edge.

Suitability for Bog Garden

This suits wildlife and natural-style bog gardens. It fills bare muddy spots, softens hard edges, and gives small flowers that sit well with grasses and rushes.

Use it at the front edge where it can creep without smothering taller plants, and keep an eye on it in tiny bog gardens where space is tight.

FAQs

What are marginal pond plants?

Marginal pond plants grow around the shallow edges of ponds, with their roots and crowns in or close to the water while their leaves and flowers grow above the surface. They are ideal for planting on pond shelves and help soften the transition between the pond and surrounding garden.

How deep should marginal pond plants be planted?

The correct planting depth varies between species. Some marginals prefer their crowns only just below the water surface, while others tolerate deeper water. Always check the recommended planting depth for the individual plant rather than placing all marginal plants at the same depth.

Can marginal pond plants grow in a wildlife pond?

Yes. Marginal plants are particularly valuable in wildlife ponds because their foliage provides cover around the pond edge and their stems can give emerging aquatic insects a route out of the water. Flowering species can also provide food for bees, hoverflies and other pollinators.

Do marginal pond plants need aquatic baskets?

Marginal plants are commonly grown in aquatic baskets, especially in lined ponds. Baskets make plants easier to position, lift and divide and can help contain vigorous roots. They should normally be filled with suitable aquatic compost or heavy loam rather than ordinary multipurpose compost.

When should I cut back marginal pond plants?

Dead or dying foliage can be removed as plants die back, particularly in autumn, to reduce the amount of decaying material entering the pond. Vigorous marginal plants can also be thinned or divided when they become overcrowded.

What are the best pond plants for a wildlife pond?

The best wildlife pond plants provide a mixture of underwater cover, surface shade, flowering habitat and places for aquatic insects to emerge. A balanced pond can include oxygenating plants, marginal plants and floating-leaved plants such as water lilies. Native species are particularly useful for supporting UK pond wildlife.
