Taxonomic Information

Appearance

Geocaulon plants have a unique appearance that sets them apart from other plants. They have a rosette of basal leaves that are arranged in a circular pattern, with each leaf being up to 10 cm long and 2 cm wide. The leaves are green in color and are deeply lobed, giving them a palmate appearance. In the spring, the plant produces a tall, slender stalk that can reach up to 60 cm in height. At the top of the stalk, there is a cluster of small white or pink flowers that give way to small, dry capsules containing the plant’s seeds.
