Native to California, and currently found only in that state.
A perennial plant that reproduces from seeds. Foliage dies back in the winter with new growth each spring from the roots. Not considered a noxious weed problem with its limited distribution.
Mature plants are robust and heavy-leaved, growing to only 2 to 3 feet in height. Several strong stems arise from the base with some branching above this. The leaves are opposite on thick, short stalks, and the leaves are about 12 inches long and elongate with rounded tips. Both sides of the leaf are densely covered with short, soft hairs. Flowers are pinkish brown and grow in thick clusters that arise from the leaf axils, each flower on a thin stalk. The huge seed pods are 4 to 5 inches long and elongate pear-shaped, opening to release the seeds, which have long silky strands attached that enable them to be carried by the wind for dispersal.
Characteristicts Important to Control:
Individual plants can be physically removed, but a systemic herbicide will be needed to kill the root system of the weed. Not generally a plant needing control.
