It is a perennial plant (who lives several years) with an underground stem (so - called rhizomes) that arise from the numerous shoots air, straight, cylindrical, green, though slightly reddish, a little more than half a meter in height. The leaves, two by two, one against another, there are some thickening of the stem (knots) very prominent. They are elongated, oval, finishing with the tip, with nervación parallel. The flowers, pale pink, with 5 beautiful petals, are clustered toward the top of the stems, flower stems arise from the same knots that the leaves. Pollination is carried out a moth that after sucking nectar with its long tongue, put the eggs inside the flower to ensure food for the larvae when they emerge from eggs. The fruit is a capsule which is elongated in the opening four cracks laying off the seeds. Its roots, long, branched hanging from the rhizome. They are able to find water which is very deep, so if planted in a garden, care should be taken with the neighboring plants, as it can steal all the water and also invade the entire land available.
