Heteranthera zosterifolia is a beautiful stem plant with bright green lanceolate leaves. In its country of origin, Brazil, it usually grows in stangant waters and swampy regions. H. zosterifolia is a relatively undemanding plant and grows well at medium light intensities without additional CO2 fertlisation. It attains its full potential, however, under strong lights and with CO2 fertilisation, then it shows lush, intensive growth and larger leaves. When allowed to grow out of the water it will often get nice blue flowers
Heteranthera zosterifolia from South America is an especially beautiful aquarium plant. It ramifies well, which results in dense bushy plant groups after only a short time. Under strong lights it grows fast and needs frequent trimming to ensure that the lower leaves are still reached by the light. It often throws water roots on the stems. On shoots floating on the water surface, small blue flowers will grow above the waterline.
