FAQs

Please read our FAQs page to find out more.

Is Butomus a bulb or a pond plant?

Butomus, also called flowering rush, is a rhizomatous pond plant rather than a traditional flower bulb. It is supplied as a root section that establishes in wet mud or shallow water and produces upright, grass-like foliage.

Where should I plant Butomus in my pond?

Plant Butomus at the pond margin in fertile mud, or position it in shallow water up to 25cm deep. A sunny location gives the strongest growth and best chance of summer flowers.

It can grow in water, but not like a floating plant. Secure the rhizome in a pond basket filled with aquatic soil or into the muddy pond edge, then place it in the shallow marginal zone. Do not leave the roots loose on the water surface.

Can Butomus grow in normal garden soil?

Butomus needs permanently wet conditions, so it is not suitable for an ordinary dry border. It can be grown in a bog garden, a container without drainage or at the edge of a pond, as long as the soil stays wet.

Why has my Butomus not grown or flowered yet?

Butomus can take time to settle after planting, especially if the rhizome has been planted too deeply or is not receiving enough sun. Check that it is in shallow water or wet mud, not deep water, and allow a full growing season for it to establish.

Does Butomus come back every year?
