Propagation
Sow fresh seed during early spring and pre-soak seeds in heated water 13º to 18ºC (55º-64ºF) for 24 hours. Seeds may require scarification.

Take soft tip cuttings of non-flowering shoots during spring and stem cuttings during summer.

Note:
Care should be taken when selecting a site as sweet potato dislikes soil that is high in aluminium and requires an application of lime. It also dislikes wet soils and a sudden burst of rain and during late summer may cause of the tubers to split open.

The tubers should be cured at 27º C. ( 81º F)for 10 days and under ideal conditions sweet potatoes can be stored for 6 to 7 months, avoid chilling the fruit is this encourages rot.

Botanic information
Leaf: The variable dark green broad-ovate to palmately lobed leaves are up to 150 mm (6 in) long by 130 mm (5? in) wide with a truncated or cordate base and a petiole up to 200 mm long. The lobed margins vary from broad-ovate to linear lanceolate with an acuminate apex and the leaves are arranged oppositely or spirally along the slender stems.

Flower: The white to lavender funnelform flowers have a purplish throat and are up to 50 mm (2 in) long with 5-stamens of unequil length and attached at the base of the petals. The pedicle is variable in length from 30 mm (1? in) to 180 mm (7 in) and the flowers appear in the leaf axils solitary or in a small cyme from spring to summer or sporadically throughout the year in tropical regions.

Fruit: The small capsule is up to 8 mm (? in) long and contains 1-4 hard coated black seeds that are around 3 mm (2/16 in) long but is not commonly seen. The small seeds are viable but the plant can be reproduced vegetatively to maintain true to type.
