January to December


The free-floating water-soldier is a rare aquatic plant that can be found in ponds and still, open water, mostly in Central and Eastern England. It is also grown in garden ponds and often escapes. It grows beneath the water, staying submerged for most of the year. From June to August, it surfaces and flowers, displaying white blooms. Like other aquatic plants, it offers resting and sheltering places for aquatic insects like dragonfly and damselfly larvae.

What to look for

The stiff leaves of water-soldier are spear-shaped and saw-edged, and form a rosette, looking a little bit like the top of a pineapple. A solitary, white, three-petalled flower arises from this rosette.

Where to find

Native plants confined to Eastern England; garden escapees more widespread.

Did you know?

Water-soldier mainly reproduces asexually in the UK, budding to produce three or four new plants each year. It can reproduce sexually, but almost all of our plants are female.
