Annonaceae
How to identify an atemoya tree
Annona × atemoya
Smoother-skinned than sugar apple, with creamy sweet flesh combining cherimoya flavor with sugar apple's heat tolerance. The most commercially successful Annona hybrid, grown in Taiwan, Israel, Australia, and Florida.
Field marks
These features are typical of the genus Annona, so they help confirm you are looking at the right group; the fruit and the details below separate the species.
- Leaves are simple and arranged alternately in two flat rows along the twig.
- Flowers usually have thick, fleshy, roughly triangular petals.
- The fruit is an aggregate of many fused segments: knobby in sugar apple, green with soft curved spines in soursop.
Check a photo
Photograph one whole, mature leaf from above, or a flower or fruit, and the identifier will return ranked matches. If atemoya is the top result, the field marks above are your second opinion.
Leaves, flowers, fruit, or bark — closer and sharper identifies better. Your photo is identified and discarded, never stored.
Where and when you will find it
- Origin / cultivation history
- Hybrid of cherimoya × sugar apple, developed in the early 20th century (Florida/Caribbean breeding)
- USDA zones
- 9b-11
- Climate
- Subtropical to tropical — more heat-tolerant than pure cherimoya, less cold-hardy.
- Fruiting season
- August, September and October (typical, Northern Hemisphere)
- How often grown
- Uncommon in cultivation
Fruit is the most reliable way to confirm an identification, so August, September and October is the easiest window. Outside it, rely on the leaves and the overall habit. A tree growing well outside the climate above is more likely to be a look-alike.
Growing it: seedling or grafted?
A young tree with no fruit is harder to identify and easy to mislabel, so it helps to know how long it takes to reach fruiting age and how it is usually propagated.
- Years to first fruit
- Grafted 2-3 yrs
- Propagation
- Grafting; often benefits from hand pollination like cherimoya.
