Description of Acorus calamus 'Argenteostriatus' (Silver-striped Sweet Flag)

Acorus calamus 'Argenteostriatus' is a variegated sweet flag with narrow leaves striped cream and green. It’s grown for foliage, not flowers, and it gives you a clean, grassy look at the pond edge.

Appearance

Leaves are upright and sword-like, often 60 to 75cm tall. The clump slowly spreads by rhizomes, so it thickens over time rather than popping up all over the place.

If you crush a leaf you may notice a scent, which is where the common name sweet flag comes from.

Care Guide

It likes wet soil and it also copes in shallow water.

  • Sun: Full sun to part shade. Colour is usually best with decent light.
  • Soil: Wet, fertile soil or aquatic compost in a basket.
  • Water depth: Boggy ground up to roughly 20cm of water over the soil line.
  • Tidy up: Comb out old leaves in late winter and remove any brown tips.
  • Division: Split clumps in spring if they get congested.

In baskets, top the compost with gravel so the rhizomes stay anchored.

Suitability for Bog Garden

This is a handy bog plant when you need year-round structure and a bright stripe through green planting. Use it to edge the wettest zone, or to break up blocks of plain foliage.

It’s also useful near paths because the leaves stay upright and don’t flop across walking space. In a small bog, one clump is often enough. In a bigger bed, repeat it every metre or so for rhythm.

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.
