Acca sellowiana – Pineapple Guava: An In-depth Look

Acca sellowiana, commonly known as Pineapple Guava, Feijoa, or Guavasteen, is an attractive evergreen shrub or small tree valued for its ornamental appeal, edible fruit, and adaptability. Native to South America, it is widely cultivated for its sweet, aromatic fruit and showy, edible flowers.

Pineapple Guava belongs to the myrtle family (Myrtaceae), which includes popular shrubs and trees such as Myrtle (Myrtus communis), Rainbow Eucalyptus (Eucalyptus deglupta), and bottlebrush (Callistemon spp.).

Native Range

Pineapple Guava originates from the highlands of southern Brazil, Paraguay, Uruguay, and northern Argentina. It thrives in subtropical and warm temperate climates.

Plant Type and Habit

It is a slow to moderate-growing, evergreen shrub or small tree with a dense, rounded or spreading habit. Its silver-green foliage adds year-round visual interest.

Size

Pineapple Guava typically grows 6 to 15 feet (1.8 to 4.6 meters) tall and wide, though it can reach up to 20 feet (6 meters) in warmer climates. It has a moderate to fast growth rate, typically adding up to 2 feet (60 cm) per year under optimal conditions. This versatile plant can be pruned into a hedge, trained as an espalier, or grown as a specimen tree

Lifespan

Pineapple Guava has a lifespan of several decades. Some plants have been known to thrive for over 50 years under optimal conditions, showcasing their resilience and adaptability to various environments.

Flowers

The tree produces striking, bicolor flowers that measure 1 inch (2.5 cm) in diameter. Each blossom features four fleshy, slightly reflexed white petals tinged with pink and a dramatic cluster of bright red stamens tipped with golden-yellow pollen.

Blooming occurs from late spring to early summer, often in small clusters nestled in the leaf axils. These eye-catching flowers stand out against the silvery-green foliage, adding a dazzling touch to the landscape.

The delicately sweet, edible petals can be enjoyed fresh in salads, desserts, or as a decorative garnish.

Fruits

Pineapple Guava produces small, oval to pear-shaped fruits that are typically 1-3 inches (2.5-7.5 cm) long and weigh between 25-60 grams. The skin is waxy, blue-green to gray-green, sometimes with reddish patches, and is easily bruised. The flesh is juicy and granular, with a sweet-tart, tropical flavor reminiscent of pineapple, strawberry, kiwi, and mint. The fruits or Feijoas are eaten raw, used in jams, jellies, desserts, and as a topping for various dishes

Foliage

Harvesting Pineapple Guava Fruit

Pineapple guava fruits ripen in late summer to fall, typically taking 4-7 months to mature. The best way to determine ripeness is when the fruit naturally drops from the tree. Ripe fruits are firm yet slightly soft, with a fragrant aroma. To harvest, gently shake the tree or pick fruits by hand when they detach easily. For the best flavor, allow fruits to ripen at room temperature before consuming. Enjoy them fresh, in smoothies, or in desserts.


How to Propagate Pineapple Guava

Pineapple guava (Acca sellowiana) can be propagated by seeds or cuttings. While seeds take longer to mature into fruit-bearing plants, cuttings ensure faster growth and retain the characteristics of the parent plant.

Propagation by Seeds

  • Seed Collection: Harvest fully ripe fruits and extract the seeds. Rinse them thoroughly to remove any pulp.
  • Sowing: Plant seeds in a well-draining potting mix at a depth of 1 to 1.5 inches (2.5-4 cm).
  • Germination: Keep the soil moist and maintain a warm temperature (70-85°F or 21-29°C). Seeds usually germinate in 3 to 4 weeks.
  • Transplanting: Once seedlings have at least two sets of true leaves, transplant them into larger pots or directly into the garden.
  • Time to Fruiting: Seed-grown plants may take 4 to 7 years to bear fruit and may not always retain the traits of the parent plant.

Propagation by Cuttings

  • Cutting Selection: Take 4-6 inch (10-15 cm) semi-hardwood cuttings from the current year’s growth in late summer.
  • Preparation: Remove the lower leaves and dip the cut end into rooting hormone to encourage root development.
  • Planting: Insert cuttings into a mix of perlite and peat moss or a well-draining propagation medium.
  • Humidity & Warmth: Keep the cuttings in a warm, humid environment with indirect light. Cover with a plastic dome or bag to retain moisture.
  • Root Development: Roots typically develop in 6-8 weeks. Once established, transplant into individual pots before moving to the garden.

Frequently Asked Questions About Pineapple Guava

Can you eat a pineapple guava?

Yes, pineapple guava (Acca sellowiana) is completely edible. The sweet, aromatic fruit can be eaten fresh by cutting it in half and scooping out the pulp. The slightly tart skin is also edible, though some prefer to remove it. Additionally, the flowers are edible and have a mild, sweet flavor.

Is pineapple guava the same as feijoa?

Yes, pineapple guava and feijoa are the same plant. The botanical name is Acca sellowiana, but it is commonly called feijoa, pineapple guava, or guavasteen. Despite the name, it is not a true guava (Psidium guajava).

What does a pineapple guava taste like?

The fruit has a unique tropical flavor that combines notes of pineapple, guava, and strawberry with a hint of spearmint. The inner flesh is juicy and slightly grainy, while the outer skin can be tart. Fully ripened fruit has a stronger fragrance and sweeter taste.

What is the difference between guava and pineapple guava?

While both belong to the myrtle family (Myrtaceae), guava (Psidium guajava) and pineapple guava (Acca sellowiana) are different species. Guava is native to tropical regions, has a softer, rounder fruit, and often has pink or white flesh. Pineapple guava is more cold-hardy, has a waxy green skin, and a unique tropical flavor profile.

Do you need two pineapple guava trees for fruit?

Some varieties of pineapple guava are self-pollinating, but cross-pollination between two different plants typically improves fruit set and yields. If planting for maximum fruit production, it’s best to grow at least two different cultivars.

How to tell if pineapple guava is ripe?

Ripe pineapple guava fruit will have a slight give when gently squeezed and will emit a strong, sweet fragrance. The fruit naturally falls from the tree when fully ripe. If harvesting early, let it soften at room temperature before eating.
