Croton texensis, despite being annual, grows larger than the related perennial C. dioicus. Croton texensis has verrucose fruits similar to those of the closely related C. parksii.

There is a single specimen of Croton texensis from Massachusetts, collected at a dump in Boston in 1890, but the species did not become established there.
