How long does it take for Vinca rosea to bloom and produce seeds?

1. How long does it take to produce seeds?

Catharanthus roseus can bloom all year round and usually produces seeds after flowering, which take 2 to 3 months to mature. When the seed coat turns yellow and black seeds can be seen inside, it means it is ripe and should be collected immediately.

2. How to produce seeds

The vinca roseus grown in ordinary households rarely produces seeds because its pollination success rate is extremely low. Artificial pollination is required to produce seeds. When pollinating, pick a flower and pollinate each flower on the plant one by one 1 to 2 times a day, between 8 and 9 in the morning and around 4 in the afternoon. One flower can pollinate 10 flowers, but then the pollen is gone, so throw it away and pick again. Because it blooms every year, seeds must be collected every year.
