Chinese Tallow Tree (Triadica sebifera) is an invasive weed from Asia. It usually grows about 60 feet tall. Male and female flowers are borne on the same tree. Chinese Tallow Tree is ranked 10 out of 10 on the Ogren Plant Allergy Scale, indicating that it tends to cause very severe hay fever. It typically blooms from about July through September, so if you suffer from hay fever during those months, Chinese Tallow Trees could be the culprits.
