distribution_en:
description_en: Genus of 8 species of floating, aquatic ferns found in lakes, ponds, and slow-flowing streams in both hemispheres. They have pinnately branched, floating rhizomes, with frail roots, producing 2-lobed, light green, scale-like fronds, which turn reddish brown in autumn. On a pool, they provide fast-growing surface cover, which partially suppresses algae and helps clear the water. In frost-prone areas only A. filiculoides is suitable for outdoor pools; grow tender species in indoor pools in a cool or temperate conservatory or terrarium.
hardiness_en: Half hardy to frost tender.
cultivation_en:
propagation_en: Scatter small bunches of young plants on the water surface in early summer.
