How it Grows

The plant flowers in warm weather, followed by round to oval fruit that ripens to deep purple when ready to pick. It is best suited to frost-free or subtropical climates but can be grown in large pots and protected during cold weather in cooler regions.

How to Grow From Seed:

Sow seeds in spring or early summer. To improve germination, soak the seeds in warm water for 24 hours before planting.

Plant about 1 cm deep in seed-raising mix and keep the soil moist and warm, around 20–25°C.

Germination can take 2–6 weeks.

Once seedlings are large enough to handle, transplant them into larger pots and then into the garden once the weather is warm and settled.

Provide a strong trellis or fence for support. Regular watering and feeding during the growing season will ensure healthy vines and abundant fruit. Mulch well to conserve moisture and suppress weeds.
