- Urena lobata is an erect shrub that grows up to 10 ft. (3 m) in height. The plant is single stalked, with free-branching stems that comprise a bushy appearance. It grows as an annual species in many areas of Florida but may perennate in south Florida.
- The leaves are palmately lobed, pubescent with stellate hairs, and 1.6-3.1 in. (4-8 cm) long.
- Flowers are borne in axillary clusters, pinkish-violet, about 0.4 in. (1 cm) across.
- Fruit is pubescent with hooked bristles or barbs that cling to clothing or fur.
- Ecological Threat
- Urena lobata invades disturbed areas, pastures, eroded areas, and perennial crop plantations. Urena lobata tolerates salt spray but does not grow in saturated soils. Having an aggressive habit, this weed grows rapidly and can reach 2-7 ft. (0.6-2.1 m) by the end of the first year.
