Ecology

Habitat

In the Coastal Plain in Florida and Georgia, T. urticifolia can be found in limestone glades, recently burned pine-oak woods, longleaf pine forests, and in pine savannas (FSU Herbarium). It has been recorded to grow in sandy loam and clay loam soils (FSU Herbarium; Miller et al. 1999). Associated species include shortleaf pine, red oak, post oak, mockernut hickory, and longleaf pine (FSU Herbarium).
