Whorled Marshpennywort - Hydrocotyle Verticillata

Some people consider whorled marshpenny to be a moderately difficult plant to grow but as long as you get the lighting right it will tolerate a wide variety of conditions.  Naturally it grows both as a bog plant and as a submerged plant in fast flowing rivers.  If planted under strong lights it will grow to about one and half inches in height but will grow taller and stringy under poor light.  This is a slow growing plant that spreads but is easily controlled.
