The piggy-back plant (Tolmiea menziesii, or youth-on-age) is a small perennial with flowering stems that can reach 40 to 80 centimeters tall. Primary leaves are hariy and basal, with hairy stalks. They are heart-shaped with palmate veination, and can have five to seven lobes with coarsely toothed margins. They can get to 10 centimeters long and sometimes have buds at the base of the blade. The flowers it produces are purple-brown, six to 10 millimeters long, with four ribbon-like petals and three stamen.
