Native range

South America east of the Andes — Brazil throughout, from the north and north-east down through the west-centre and south-east to the southern states, and on through Bolivia, Paraguay, Uruguay and northern Argentina, with outlying populations in Guyana and French Guiana — in forest, usually primary but also in more open ground, favouring moist rocky soils.

Spacing

400 cm (157 in) apart — about 16 m² (172 sq ft) per plant

Leaf shape

Alternate and trifoliate: three saw-toothed leaflets on a single stalk, the terminal one largest, giving the crown a light feathered texture. It is the field mark for the genus and separates chal-chal at a glance from anything it grows beside.

Root system

Moderately deep and drought-tolerant once established, matching the seasonally dry forest it comes from. Detailed root descriptions are not published for the species — this is inference from its habitat and behaviour in cultivation rather than a documented account.

Fruit description

Small round berries 5–8 mm in short clusters, ripening yellow through red to almost black, with a thin sweet-tangy pulp over a single seed. Eaten out of hand and used in cold drinks across southern Brazil, Paraguay and Uruguay, where the leaves are brewed as well.

Propagation

Fresh seed sown into compost in shade germinates reasonably, but the seed does not store — sow it as soon as it is clean. Semi-hardwood cuttings are possible and less reliable.

Pollination

Insect-pollinated
