About
Tabernaemontana divaricata, commonly called pinwheel flower, crape jasmine, Ceylon jasmine, East India rosebay, and Nero's crown, is an evergreen shrub or small tree native to South Asia, Southeast Asia and China. In zones where it is not hardy it is grown as a house/glasshouse plant for its attractive flowers and foliage. The stem exudes a milky latex when broken, whence comes the name milk flower.
Safety
The species is known to produce many alkaloids including catharanthine, conolidine, coronaridine, dregamine, ibogamine, tabersonine, voacangine, voacamine and voacristine. Ibogaine may occur in multiple Tabernaemontana species.
