Camu camu is a branched shrub or small tree commonly about 2–4 m tall. Its small fruits mature from red or maroon to purple-black and contain soft, juicy, sweet-to-acid pulp.

Camu camu (Myrciaria dubia) is an evergreen Amazonian shrub or small tree in the genus Myrciaria, family Myrtaceae, and order Myrtales. It is adapted to periodically flooded river margins, a habitat distinction that matters when translating its wet-root ecology into garden or container culture.[1][2]
Description[edit | edit source]
Camu camu is a branched shrub or small tree commonly about 2–4 m tall. Its small fruits mature from red or maroon to purple-black and contain soft, juicy, sweet-to-acid pulp. The fruit is the feature most often associated with the crop, but the plant's floodplain habit is equally important for cultivation planning.[2]
Distribution and habitat[edit | edit source]
The species is native across parts of northern and western South America, including Amazonian Brazil, Peru, Colombia, Ecuador, Venezuela, and Guyana. It commonly grows along rivers and in flooded forest, where lower stems or the root zone may be periodically immersed. Do not transfer dryland guava or Eugenia irrigation schedules to this species without accounting for that habitat.[1][2]
Cultivation[edit | edit source]
Camu camu needs reliable moisture and high atmospheric humidity. In an upland garden, reproduce the moisture-retentive, organic conditions of a floodplain without allowing a small container to become stagnant and anaerobic. The species is better suited to warm, humid climates than to dry interiors or cold winter sites.[2]
Soil and water[edit | edit source]
Use a deep, fertile, humus-rich medium that stays moist. Floodplain plants can tolerate periodic inundation, but a pot or raised bed still needs enough aeration to avoid sour, stagnant conditions. The reviewed tropical-plant account notes a high iron demand; this is a source-specific observation, not a reason to add iron without a soil test. Protect young plants from drying out while roots establish.[2]
Sun and humidity[edit | edit source]
Bright light or full sun is useful where water supply is dependable. Native river margins are humid and open to intermittent light, but dense wet foliage should still have airflow. In dry climates, wind protection and humidity management are more important than simply adding irrigation to an exposed site.[2]
Seasonal changes[edit | edit source]
The species' seasonal cycle follows river level and floodplain wetness rather than a single universal dry- or cool-season calendar. Flowering and harvest timing varies among river systems and was not established reliably in this research pass. Maintain moisture during local dry periods and protect the root zone from abrupt drying; reduce no water solely because the plant is grown in a container unless the plant's condition and drainage call for it.[2]
Propagation[edit | edit source]
Seed, cuttings, and side-veneer grafting are documented. Fresh seed is preferred for viability, while vegetative methods are useful when a productive plant is being preserved. No universal germination schedule, rooting percentage, or grafting success rate is asserted here. Years to fruit is recorded as N/A because no reliable species-wide first-fruiting value was verified.[2]
Flowering, fruiting, and harvest[edit | edit source]
Camu camu produces small fruits that become maroon to purple-black when ripe. A general flowering or harvest month range could not be defended across the species' broad floodplain distribution. Record local river-stage, flowering, and color-change observations rather than applying a calendar from another Amazonian region. Harvest ripe fruit for fresh use or processing, handling the soft fruit gently.[2]
Fruit and uses[edit | edit source]
The fruit is eaten fresh and used in beverages, concentrates, and vitamin-C products. The pulp is notably acidic, so it is often combined with sweeter ingredients in drinks and preserves. Food-processing claims should not be extended to medicinal dosage or therapeutic efficacy without separate evidence.[2]
