Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Cultivation details

Requires a sunny or lightly shaded position in still or slowly flowing water. Plants are not very cold tolerant, surviving overwintering in colder winter areas by means of submerged resting buds[200]. Plants seldom reproduce by spores[200]. This species has a symbiotic relationship with an algae which fixes atmospheric nitrogen[200].

Azolla is a fern and should have spore-producing organs rather than flowers. .

Azolla is an invasive non-native species in Britain, so we should either not use it at all, or use it with extreme caution. See for example link below.
