Fontinalis antipyretica ‘Willow’

Description

Reading Time: 1

Fontinalis antipyretica has branched, trailing stems that are triangular in cross-section and may be as long as 60 cm (24 in). The leaves are quite stiff and are arranged in three overlapping rows. Each leaf is lance-shaped or egg-shaped, with a keel and a sharp point, some 4 to 9 mm (0.16 to 0.35 in) long. There are no flowers but minute spores are sometimes produced in smooth sporangia (capsules) between 2 and 2.6 mm (0.08 and 0.10 in) long.

Fontinalis antipyretica is found in North America as far south as Pennsylvania and Arizona, and also in Europe, Asia and parts of Africa. It grows attached to submerged rocks in fast-flowing water. It also occurs attached to the substrate in lakes and as floating masses in still water, and may be cast up on beaches at the waterside. It thrives in shady positions and prefers acid water, a pH of around 8.4 being the maximum tolerated.
