About

Stratiotes aloides, commonly known as water-soldier or water pineapple, is a submerged aquatic plant native to Europe and northwestern Asia. In Britain it was once common in East Anglia and still is in many places, particularly wet ditches and healthy ponds. It is the only species in the genus Stratiotes.

How to grow it

Most suitable for the cool aquarium or pond.

Propagation from runners which form from the centre of the rosette of leaves.

Where it grows

In Ireland, it is found in shallow waters where it was introduced. Apparently now extinct in the north-east of Ireland. Rare in east England.
