Aridarum caulescens
Is a very floriferous aquarium plant. Tied to wood or a porous stone with a fishing line, the firm and tight rhizome can grow into place. It grows really very slowly and is also quite undemanding. The elongated, pointed leaves of about 5cm have a stalk that is just as long and outgrows the rhizome quite stiffly. It doesn't need a lot of light, and even CO2 isn't absolutely necessary. Seldom available in stores and therefore sold out quickly, but always worth a recommendation.
