(Redirected from Acca sellowiana)

The accepted name for this species has oscillated somewhat over the years between Feijoa sellowiana and Acca sellowiana (O.Berg) Burret. As of 2024 the name has reverted to Feijoa sellowiana (see Lucas E.J. et al, A New Subtribal Classification of Tribe Myrteae (Myrtaceae), Systematic Botany (2019), 44(3): pp. 560-569)

Common Name: Feijoa

General Information

Feijoa sellowiana is a densely-branched, evergreen shrub or small tree with a very dense, rounded crown; it can grow 3 - 7.5 metres tall. The short, cylindrical bole can be 15 - 20cm in diameter[, ].
The edible fruit is much appreciated within the plants native range. The plant is sometimes cultivated in warm temperate to tropical regions, both for its edible fruit and also as an ornamental plant, where it is valued especially for its very attractive flowers.
Feijoa sellowiana has a very wide distribution, large population, is not currently experiencing any major threats and no significant future threats have been identified. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2019)[].

Cultivation Details

Feijoa grows best in warm temperate, subtropical and cool, highland tropical climates, generally not fruiting very well at lowland elevations in the tropics[]. It grows best in areas where annual daytime temperatures are within the range 18 - 21°c, but can tolerate 12 - 28°c[]. When dormant, the plant can survive temperatures down to about -10°c, but young growth can be severely damaged at -1°c[, ]. It prefers a mean annual rainfall in the range 750 - 1,500mm, but tolerates 600 - 2,000mm[].
Prefers a light loamy well-drained soil[, ], requiring a warm sunny position[]. Prefers light shade[]. Succeeds in any reasonably good soil, even growing well on chalk[, ]. Prefers a pH in the range 5.5 - 7, tolerating 4.5 - 8[, ]. Dislikes extreme alkalinity[]. Tolerates drought and salt winds[].
Plants are generally quite slow-growing[].
Plants can commence fruiting when 3 or more years old from seed[].
There are some named varieties, developed for their superior fruiting[].
Some cultivars are self-fertile whilst others require cross-pollination[].

Edible Uses

Fruit - raw or cooked[, , ]. A delicious aromatic taste, somewhat like a cross between a pineapple and a strawberry[]. The fruit is best eaten raw but it can also be made into pies, cakes, puddings, jams, jellies etc[]. Fruits can suffer damage from autumn frosts, though the flavour develops better at low temperatures[]. The fruit is up to 7.5cm long[]. It is a rich source of iodine.

Flowers - raw[, , ]. The petals are sweet, crisp and delicious, they taste more like a fruit than many fruits[]. They should be harvested just after they begin to soften[]. (not sure that I agree with this last sentence[])

Medicinal

The plant is astringent. A decoction of the buds is used to treat diarrhoea[].

Flavonoids with antimicrobial and antioxidant properties have been detected in the fruits[].
Fruit skin extracts have shown antitumour and antimicrobial properties[].

Agroforestry Uses:

Feijoa has a dense growth habit, resists maritime exposure and responds well to trimming. It can be grown as a shelter hedge in mild maritime areas[, ].
The shallow root system holds the soil and prevents erosion[].

Other Uses

The wood is moderately heavy, compact, elastic, splits easily, very durable even in adverse conditions. It can be used for small works, posts, stays etc[].
The wood is used for fuel and to make charcoal[].

Propagation

Seed - sow in containers. Rinse the seed before sowing to ensure there is no fruit flesh remaining since this can inhibit germination. The seed usually germinates in 3 - 6 weeks at 15°c[]. Prick out the seedlings into individual pots as soon as they are large enough to handle. Grow on until large enough to plant out in permanent positions.
Cuttings of half-ripe wood, 5 - 7 cm with a heel. Slow to root[], but you eventually get a good percentage take[].
