Habit
This erect perennial can be found flowering during most of the year. It may act as a summer annual in cooler climates.
Leaves
The alternate leaves are composed of three heart-shaped leaflets. They can range in color from green to purple. The leaf margins can be fringed with hairs.
Identifying Characteristics
When exposed to full sunlight, or drought conditions, the leaves will turn reddish and wilt. The stems are hairy and are usually green, but can be pink.
Flower Seed Head
The yellow flowers form in clusters on slender stalks. The flowers generally grow in clusters of 1-5 and have 5 petals.
Seed Fruit
Seeds come from angulated, cylindrical, hairy seedpods, resembling okra. The seedpods can grow from 1/3 to 1 inch in length. Each pod may contain from 10-50 seeds, and when ripe, will expel them with great force up to 13 feet away. Because of the rough surface of the seeds, they tend to adhere to surfaces they encounter.
Where Found
This plant can be found growing in shady areas or in full sunlight if there is enough moisture.
