Frequently Asked Questions

Do I need to repot the plant when it arrives?

No. Both the 1 litre and 3 litre sizes can go straight into the pond in their mesh basket without repotting, though 1 litre plants that grow past around 60cm in height benefit from a larger basket or planting in gravel so they don't fall over in a breeze.

How deep should I plant it?

Place 1 litre plants no deeper than half the maximum recommended planting depth to start with, then lower them as they establish. 3 litre plants can be placed directly on the pond shelf at the full recommended depth straight away.

When does it flower?

It produces small, horn-shaped green blooms in June and July, above the upright green foliage.

How much care does it need?

Very little. Once the foliage dies back in autumn, trim it back close to the water's surface, leaving some material in place to protect the new shoots that emerge the following year.

Is this plant native to the UK?

It's classed as naturalised rather than a UK native, having become established here over time.

A low-maintenance marginal pond plant, supplied already potted in its mesh aquatic basket, that gives upright green structure to a pond edge without much upkeep. Suited to full sun or part shade, it helps bring naturalised planting to the margin or shelf with very little ongoing attention.

Acorus calamus is an upright marginal pond plant with iris-like green foliage, topped in early summer by a small, horn-shaped green bloom, and grown from a rhizome that spreads across the ground as the leaves rise up from it. It's one of the few pond marginals with a long history of use in fragrances and traditional remedies, dating back to Egyptian times. Suited to pond margins in full sun or part shade, it helps add vertical structure and ground cover around the water's edge while asking very little of you in return.

You get one plant, already potted in a mesh aquatic basket sized to whichever option you choose, ready to go straight onto the pond shelf or margin. There's no need to remove the basket before planting, and no repotting is needed when it arrives.

Once the foliage dies back in autumn, trim it back close to the water's surface, leaving a little material in place to protect the new shoots that come through the following year. Left alone it spreads at a steady, medium pace rather than taking over a planting pocket quickly.
