| Scientific name | Annona cherimola |
| Common names | Cherimoya, cherimoyer, chirimoya |
| Genus | Annona |

| Order | Magnoliales |
| Native range | Bolivia, Colombia, Ecuador, and Peru[1] |
| Growth form | Low-branched, briefly deciduous or semi-deciduous tree[2] |
| Climate and site | Mild subtropical or highland tropical; good drainage and protection from strong winds[2] |
| Mature height | Commonly about 3 to 10 m[3] |
| Soil | Sandy loam or decomposed granite with good drainage; pH 5 to 8 is given for the Ventura production region[2] |

| Harvest | Fruit commonly ripens 5 to 8 months after pollination and continues to soften after picking[2][4] |
Annona cherimola is the cherimoya, a low-branched Andean fruit tree grown for its fragrant flowers and soft, sweet fruit. Its highland climate, seasonal leaf loss, and protogynous flowers distinguish it from hotter-climate annonas such as sugar apple.[1][2]
Description[edit | edit source]
The tree is erect but often low-branched, somewhat shrubby, or spreading, with rusty-hairy young branchlets. It commonly reaches about 3 to 10 m. Leaves are alternate, and the fragrant flowers occur singly or in small groups. The species is briefly deciduous or semi-deciduous in some production climates.[2][3]
Distribution and habitat[edit | edit source]
Annona cherimola is native to Bolivia, Colombia, Ecuador, and Peru. It is associated with inter-Andean valleys and other highland sites rather than hot, wet lowlands. Ventura County production guidance places cherimoya in a high-elevation tropical setting with a seasonal growth rhythm.[1][2]
Cultivation[edit | edit source]
Soil and water[edit | edit source]
Use a well-drained medium such as sandy loam or decomposed granite. Ventura County guidance gives a pH range of 5 to 8 for its production region and emphasizes drainage. In cultivation, water young trees during establishment while allowing the root zone to drain between irrigations rather than keeping it saturated.[2]
Sun and humidity[edit | edit source]
Provide bright exposure with shelter from strong winds. Air movement is useful where humidity remains high, while hot, drying conditions during bloom can reduce reliable fruit set. Highland conditions are cooler than a hot lowland tropical climate, so warm sites need especially careful attention to airflow and root-zone drainage.[2]
Seasonal changes[edit | edit source]
Cherimoya may shed its leaves during a seasonal transition, with flowering following the vegetative cycle. Flowering dates vary among regions and climates. Adjust irrigation to the local wet and dry or cool and warm rhythm rather than treating the tree as continuously growing, and protect young trees from frost.[2]
Propagation[edit | edit source]
Propagation by seed is documented for the species. Cuttings are difficult, so a cutting that fails to root should not be treated as evidence that the seed-propagation route is unsuitable.[2][3]
Flowering, fruiting, and harvest[edit | edit source]
Cherimoya flowers are protogynous: the stigmas become receptive before the anthers release usable pollen. This timing makes hand pollination important in many orchards. Fruit commonly takes about 5 to 8 months to ripen after pollination, with timing affected by cultivar, latitude, temperature, and site.[2]
Harvest fruit when it is full-grown and still firm. Cherimoya is climacteric and continues to soften after picking; room-temperature ripening takes about 6 to 7 days. Handle ripe fruit carefully because bruising and browning develop quickly.[2][4]
Fruit and uses[edit | edit source]
Ripe cherimoya flesh is usually eaten fresh with a spoon. It is also used in sherbet, ice cream, fruit salads, and beverages. The hard seeds should be removed and discarded; the seeds and other plant parts are not treated as food because poisonous alkaloids have been reported in them.[2][3]
