Heteranthera zosterifolia "Star Grass"

Heteranthera zosterifolia is a beautiful stem plant with bright green lanceolate leaves. In its country of origin, Brazil, it usually grows in stagnant waters and swampy regions. H. zosterifolia is a relatively undemanding plant and grows well at medium light intensities without additional CO2 fertilization. It attains its full potential, however, under strong lights and with CO2 fertilization, then it shows lush, intensive growth and larger leaves. When allowed to grow out of the water it will often get nice blue flowers.
