Plants reach about 3 m height with 3.5 cm stem diameter in 2 years, in 4 years about 5 m height and 7 cm stem diameter. Flowering and fruiting is almost throughout the year, but in India there Seeds are usually two main flowering periodsgenerally directly sown, one in the early monsoon and another in the late monsoonseeds may require scarification.<ref name="How to plant/cultivateCultivation details"/>
