Eugenia selloi, known in Brazil as pitanga-tuba or pitangatuba, is an evergreen shrub or small tree in the myrtle family, Myrtaceae. It is native to eastern Brazil, where it grows in forest habitats, and is occasionally cultivated for its edible, acidic fruit.[2]

Description[edit | edit source]

The plant is usually a shrub about 1–2 m tall, described in a broad horticultural account as evergreen and sometimes a small tree.[2] Fruit used in research at a São Paulo farm came from plants about 2 m tall with dark green leaves,[3] and a later study places the species at up to about 2.5 m.[4] The fruit is a berry with a thin skin and thick, juicy pulp. Studied fruit was oblong, bright yellow, about 4 cm long and 3 cm wide, with an intense bittersweet scent;[3][4] a broader account lists white or yellow fruit about 7 cm by 5 cm, so reported size and color vary with the account and form.[2]

Cultivation[edit | edit source]

The species is native to Atlantic-forest country in eastern Brazil; the fruit used in the studies came from a subtropical Atlantic-rainforest farm at about 612 m elevation in Campina do Monte Alegre, São Paulo.[3]

Soil and water[edit | edit source]

The native setting is moist Atlantic forest rather than dry or waterlogged ground. As a habitat-based inference, a moisture-retentive but freely draining soil with organic matter is a reasonable starting point; confirm this for the individual site and container rather than treating drainage or irrigation as fixed requirements.[3]

Sun and humidity[edit | edit source]

Several coastal California growers find the plant grows and fruits better with dappled light or part-day shade than in full sun. In one report, matched 25-gallon plants on a west wall with midday shade protection fruited well while the same plants in full sun set no fruit; other growers saw full-sun leaves burn and defoliate before regrowing, and a greenhouse plant fruited well under 50% shade cloth.[5] These are first-hand reports from a mild coastal climate, not a tested universal light requirement.

Seasonal changes[edit | edit source]

Plants in mild coastal gardens kept flowering through the summer.[6] Cold response varied between reports: one seedling survived a night near −1 °C (30 °F) under 10 cm of snow without branch loss, leaves turned purple and dropped near freezing, and a small plant defoliated but regrew after below-freezing nights; an unprotected, large in-ground plant was killed near −7 °C (20 °F). An adapted in-ground plant with drip irrigation was described as dependable.[5][6] These individual outcomes do not define a tested hardiness limit.

Propagation[edit | edit source]

Seed is the documented propagation route.[2] Growers describe seedlings as slow to get going and then accelerating once established.[5] One seedling-raising grower finds pitangatuba transplants well at a small size, around the stage at which many Eugenia seedlings in the same operation are lost after the first true leaves.[7] Sow fresh, clean seed in a free-draining medium and keep it evenly moist; this is a practical starting method from the seed-propagation record rather than a tested protocol.[2]

Flowering, fruiting, and harvest[edit | edit source]

In one report, plants flowered through the summer; hand-pollinating a single bush gave only one or two fruit, and the grower then bought a second bush for cross-pollination, with self-incompatibility uncertain.[6] Small fruit that dropped green ripened on the kitchen counter in the same report, while fruit left to over-ripen turned mushy and poor-tasting.[6] Harvest as the fruit shows ripe color, and handle the thin-skinned, soft berry carefully.

Fruit and uses[edit | edit source]

The ripe fruit is eaten fresh; one grower describes an aroma like passion fruit, guava, and mango with a sour but tropical taste and soft, juicy pulp around one relatively large seed.[6] Processed uses include juices, sherbets, and jellies.[2] In Brazilian folk medicine the plant has a traditional use for skin depigmentation and vitiligo, and the fruit contains a photosensitizing substance; this is a recorded folk use, not an established treatment.[3] The trade name Starcherry was coined by a Florida nursery owner for this species, and the same nursery markets a Eugenia selloi × E. luschnathiana cross as Pitombatuba; both names are commercial claims rather than formal cultivar registrations.[8]
