Fun Facts
- 🌱 Custard apple flowers are self-incompatible and require cross-pollination; in many regions, hand-pollination with a paintbrush is necessary to ensure good fruit set
- 🌱 The fruits have an unusual segmented appearance due to the carpel-derived segments in the flower, giving them a 'warty' or scaly texture that is characteristic of Annona fruits
- 🌱 Custard apples are rich in vitamin C and contain acetogenins, compounds being researched for potential anti-cancer properties in scientific studies
