Pineapple Guava

Thrives in USDA Zones 8 - 11

• Transplant

  Plant container-grown or bare-root nursery stock in early spring after last frost, or in fall at least 6–8 weeks before first frost to allow root establishment

• Harvest

  Fruit is ripe when it drops naturally from the shrub or detaches with slight pressure; check the ground beneath the plant daily in autumn, as fallen fruit bruises quickly and should be gathered within a day or two

• Top-dress with finished compost each spring to maintain soil organic matter and slow-release nutrition without forcing excessive vegetative growth at the expense of fruit

• Apply a 3–4 inch layer of wood chip mulch over the root zone to conserve moisture, suppress weeds, and encourage the fungal soil web that supports deep-rooted shrubs

• Liquid worm casting tea applied monthly through the growing season supports steady leaf color and fruit development without salt buildup in drier soils

• Avoid high-nitrogen inputs after mid-summer, which can push soft late-season growth susceptible to cold damage in zone 8–9 gardens

• Encourage ground beetles and other beneficial insects by underplanting with low flowering herbs like thyme or creeping rosemary, which will not compete aggressively with feijoa roots

• Watering

  If dry weather lingers, let the top 2 inches start to dry before watering again. This plant often responds better to an occasional deep soak than to frequent light watering.

• Feeding

  If growth is strong, compost-rich soil often carries most of the load. If the plant starts looking pale or stalls, a light compost top-dressing or gentle organic feed may help.

• Pruning

  If pruning is needed, dormancy or the period just after harvest is often the simplest window. Dead, damaged, or crossing growth is usually the first place to start.

• Seasonal care

  In late fall, a light cleanup and fresh mulch can help if winter protection is useful in your climate. Leaving a little space around crowns and trunks often helps air move and keeps excess moisture from sitting there.

• Coolidge

  One of the most widely available self-fertile named varieties, producing medium-sized fruit reliably without a pollinator partner; flavor is classic pineapple-guava with good sweetness.

  Best for

  Single-plant gardens and containers in zones 8–10

• Mammoth

  Bears notably large fruit—among the biggest of any named feijoa variety—with rich, complex flavor; benefits from cross-pollination with another variety for best yields.

  Best for

  Growers prioritizing fruit size and maximum yield

• Nazemetz

  A California-selected variety valued for consistently large, flavorful fruit and reliable production; reported to have better heat tolerance than some other named selections.

  Best for

  Warmer Mediterranean and zone 9–10 gardens

• Apollo

  New Zealand-bred variety producing large, smooth-skinned fruit with mild, sweet flavor and low grittiness; widely grown commercially in NZ and gaining availability in North American nurseries.

  Best for

  Growers wanting mild-flavored, large fruit for fresh eating

• scale insects
• fruit flies (in coastal subtropics)
• guava moth (Coscinoptycha improbana, in some regions)
• aphids

Origin

Pineapple Guava (Acca sellowiana) originates from the highlands of southern Brazil, Uruguay, and adjacent parts of Paraguay and Argentina. It is native to subtropical and temperate regions of that area.

Native Habitat

In its native range, it grows in open woodlands, forest edges, and highland grasslands, often at elevations with cool temperatures and relatively high rainfall. It is adapted to well-drained soils in montane and sub-montane environments.

Current Distribution

It is now widely cultivated in subtropical and warm temperate regions worldwide, including parts of Europe, New Zealand, Australia, the Mediterranean, and the western United States, both as an ornamental and for its fruit.

• Root System

  Fibrous, moderately deep root system that benefits from undisturbed soil; avoid deep cultivation near established shrubs, as surface roots are easily damaged and slow to regenerate.

• Stem

  Multi-stemmed evergreen shrub reaching 8–15 feet with smooth, exfoliating grey-brown bark; prune lightly after fruiting to maintain an open canopy and encourage light penetration to fruiting wood.

• Leaves

  Opposite, leathery, oval leaves are deep glossy green on top and distinctly silvery-white beneath—this bicolor contrast is one of the easiest field identification features, and wilting or yellowing leaves in summer typically signal underwatering rather than disease.

• Flowers

  Showy mid-summer flowers have four reflexed white-and-crimson petals surrounding a prominent brush of dark red stamens; they are attractive to native bees and hummingbirds, and the fleshy petals are edible with a sweet, rose-like flavor without reducing fruit set if harvested lightly.

• Fruit

  Egg-shaped, dull green fruit 1–3 inches long with a persistent calyx at the blossom end; the surest harvest signal is natural fruit drop, after which the flesh softens from firm to yielding within 3–5 days at room temperature.

Pineapple guava originates in the highland subtropical grasslands and forest edges of southern Brazil, Uruguay, Paraguay, and northeastern Argentina, where it grows naturally at elevations between 1,000 and 4,000 feet. German botanist Friedrich Sellow collected specimens in the early nineteenth century, and the species was formally described by Otto Berg in 1859, commemorating Sellow in the epithet. It was introduced to European gardens in the 1890s and reached California and New Zealand nurseries by the early twentieth century. Unlike most subtropical fruit, it thrives in cool-summer Mediterranean climates precisely because its native altitude gives it genuine frost hardiness—a trait that makes it uniquely useful to temperate gardeners.

Indigenous and rural communities in southern Brazil and Uruguay historically utilized various parts of Acca sellowiana in folk botanical contexts, though the plant's medicinal record is far less extensive than its culinary one. Ethnobotanical surveys from the Rio Grande do Sul region of Brazil document local use of leaves prepared as infusions for their aromatic properties. The fruit's high vitamin C and polyphenol content was recognized empirically by Uruguayan and Argentine rural communities long before formal analysis.

• Rural folk botany, Rio Grande do Sul, Brazil, 19th–20th century - leaves

  Ethnobotanical surveys from the southern Brazilian highlands record leaf infusions as part of regional folk botanical practice, valued for their aromatic qualities in a region where the plant grows semi-wild.

• Uruguayan and Argentine criollo agricultural tradition - fruit

  Rural communities across the Río de la Plata region consumed fresh fruit and recognized its tart, vitamin-rich flesh as a seasonal food resource, preserving it as dulce de guayabo for winter stores.

The ripe fruit flesh, flower petals, and seeds are considered safe to eat. The skin is edible but somewhat astringent; most growers discard it. No documented toxicity is associated with this species, though individuals with sensitivities to the Myrtaceae family should exercise awareness.
