''Tabernaemontana sananho'' is a tropical shrub or small tree of northern South America. Sananho, sanangillo and uchu sananho are among its recorded names. Its native range includes lowland evergreen rainforest and other forested habitats, and a field record from Ecuador describes the plant as an understory tree. [[#cite_note-2|[2]]][[#cite_note-3|[3]]]

== Description ==

The species has repeatedly dichotomously branched growth and white, five-parted flowers. Its fleshy fruits have two narrow ridges, and the numerous ellipsoid seeds are deeply grooved on one side. These characters come from a voucher-identified plant collected at 425 m in lowland evergreen forest in Pastaza, Ecuador. [[#cite_note-3|[3]]]

== Cultivation ==

=== Soil and water ===

The lowland evergreen-rainforest setting suggests a warm root zone with dependable moisture. As a habitat-based starting point, use an organic, free-draining medium kept evenly moist while avoiding prolonged saturation. Drainage and local response matter more than a rigid watering calendar. [[#cite_note-2|[2]]][[#cite_note-3|[3]]]

=== Sun and humidity ===

Understory habitat favors bright filtered light or partial shade with warm, humid air. Acclimate gradually before attempting more direct light. This is a conservative habitat-based starting point rather than a measured shade limit. [[#cite_note-3|[3]]]

=== Seasonal changes ===

This evergreen-tropical-forest plant should be protected from chilling and root-zone drying during a pronounced dry or cool season; allow the medium to drain after irrigation. Irrigation and cold response are local cultivation variables rather than fixed species limits. [[#cite_note-2|[2]]][[#cite_note-3|[3]]]

== Propagation ==

The fruit contains numerous ellipsoid seeds deeply grooved on one side. Seed form is documented, while germination treatment and timing remain open questions for provenance-preserving trials. [[#cite_note-3|[3]]]

== Flowering, fruiting, and harvest ==

White, pentamerous flowers and fleshy fruits with two narrow ridges are documented for the species. [[#cite_note-3|[3]]]

== Fruit and uses ==

An Ecuadorian ethnobotanical record describes the fruits as sweet and eaten by several Ecuadorian peoples, while the Kew plant-use record lists the infructescences as edible fruit. These are geographically and culturally scoped food-use records rather than a general food-safety clearance. An integrative review discusses an irritant alkaloid in sananga and calls for further research; this is not a fruit-specific toxicology result or dosing guidance.
