They are perennial plant that grows at humid places such as in the forest along mountain stream and at the deep pool of mountain rivers (perennial plant takes several years to grow). They spread stalks underground transversely, and grow in colonies to sprout roots from knots. After flows bloom, the seed gets matured and cracked. The shape of cracked seeds looks like cat’s eye. This is how they are named Chrysosplenium. About 10 flowers on the top of stalk gather to bloom. Their characteristics are that flowers are about 2 mm in diameters with no flower petals, the bract leaf surrounded with 4 calyxes and flower standing out in vivid yellow-green color and that is just like a flower itself (the bract leaf: transformed leaf at the root of flower stalk). The group of Chrysosplenium usually has 8 stamens, while the original group has only 4 in typical. This helps us which one to tell. The leaf is about 0.5 to 2 cm and grows from stalk like facing each other. The leaves are wide-egg shaped and have edge-round obtuse sawtooth at the edge.
