Harvest calendar

Ripens: Late summer to autumn

Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

Fruit is spiny and unassuming outside but prized inside — a black, appreciated pulp gathered from the wild especially in Guerrero, Mexico. Dioecious: both a male and a female plant are needed for fruit to set.

300 cm (118 in) apart — about 9 m² (97 sq ft) per plant
Leaf shape
Glossy dark green, with spines in clusters of four at branch tips
Root system
Deep and drought-adapted, suited to the seasonally dry thorn scrub it grows in; established plants sit out a long dry season without help.

Pollination
Insect-pollinated. Dioecious — a female plant will not set fruit without a male nearby.

Growing guide

Growing tips. More drought-tolerant than most Rubiaceae in this catalog, reflecting its dry-forest and thorn-scrub origin rather than a rainforest understory. Fragrant white-and-yellow flowers through spring and summer draw pollinators; needs a male and female plant to fruit.

About the data

Zone figures are typical published ranges — microclimate, drainage and siting shift them by a zone in either direction. Store links are found by an automated search, refreshed every six weeks. Availability is seasonal; stock and prices are not tracked.
