About Pitomba

Eugenia luschnathiana · also called Pitomba, Peach of the tropics · tropical

Pitomba is a slow-growing Brazilian evergreen tree in the myrtle family, bearing bright orange-yellow fruit with juicy, aromatic, sweet-tart pulp. Ornamental and compact, with glossy leaves and fragrant white flowers, it is well suited to large containers in cooler climates and to frost-free gardens, where it makes both a fruiting and decorative specimen.

Cold limit: USDA 10-11 (tender; protect below about 0°C) · RHS H1b (18-30°C)

Watch for — Cold damage: As a tender tropical it is damaged by frost and chilled by temperatures near freezing. Grow in containers that can be moved indoors, or provide frost protection in marginal climates.

What pitomba's hardiness rating actually means

Pitomba is not cold hardy. It is a tropical houseplant that dies if it is left out through frost — there is no zone where it overwinters outdoors in a UK or cold-US climate. Its RHS rating of H1b means: Sub-tropical — a normal warm home is fine, but it cannot go outside in a cool season. On the US scale that maps to USDA 10-11 (tender; protect below about 0°C) — the zones where it can be left outdoors year-round.

New to these scales? The USDA hardiness zone map explained covers how the zone numbers work, and you can find your own zone with the zone finder.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about 10 °C (sustained cold below this is damaging). Pitomba has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for pitomba as it gets too cold:

Below about about 10 °C, growth stalls and the leaves start to show cold stress — dark, water-soaked, or yellowing patches.
A single light frost blackens the foliage; a hard freeze kills the whole plant, roots included, and it does not recover.
Even a cold, draughty windowsill or an unheated porch in winter can be enough to damage it permanently.

Can pitomba go outside or overwinter — and where?

It can holiday outdoors in summer once nights are reliably above 10 °C, in shade or dappled light, hardened off gradually.
Bring it back indoors well before the first autumn frost — do not wait for a frost warning, move it when nights drop toward 10-12 °C.
It will never overwinter outside in a temperate climate; the indoors is its winter home, full stop.

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when pitomba can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1b figure above.

Pitomba hardiness — frequently asked questions

Is pitomba cold hardy?

Pitomba is not cold hardy. It is a tropical houseplant that dies if it is left out through frost — there is no zone where it overwinters outdoors in a UK or cold-US climate. Indoor-only in almost every home. Pitomba can only live outside year-round in genuinely frost-free climates (roughly USDA 10-11 (tender; protect below about 0°C)); everywhere else it is a houseplant that summers out at most.

What is the minimum temperature pitomba can survive?

Minimum survivable temperature is roughly about 10 °C (sustained cold below this is damaging). Pitomba has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

What hardiness zone is pitomba?

Pitomba is rated USDA 10-11 (tender; protect below about 0°C) and RHS H1b — Sub-tropical — a normal warm home is fine, but it cannot go outside in a cool season.

Can pitomba survive winter outside?

It can holiday outdoors in summer once nights are reliably above 10 °C, in shade or dappled light, hardened off gradually. Bring it back indoors well before the first autumn frost — do not wait for a frost warning, move it when nights drop toward 10-12 °C. It will never overwinter outside in a temperate climate; the indoors is its winter home, full stop.

What happens to pitomba below its minimum temperature?

Below about about 10 °C, growth stalls and the leaves start to show cold stress — dark, water-soaked, or yellowing patches. A single light frost blackens the foliage; a hard freeze kills the whole plant, roots included, and it does not recover. Even a cold, draughty windowsill or an unheated porch in winter can be enough to damage it permanently.
