Feijoa. Acca sellowiana. Also known as Pineapple Guava.
The Feijoa is also known as a Pineapple Guava even though it is not a member of the Guava family. It is an attractive tree which can be trained to be a productive hedge, screen or windbreak. It can be espaliered, planted as a specimen plant or planted in pots over 35 litres. It likes a part shade to full sun condition in well draining soil, it can grow to around four metres high but is happy to be kept pruned at two metres.
In spring it will produce edible sweet, purple, pink and white flowers which can be used in desserts and drinks. Within around four years from planting the tree will produce egg shaped, green skinned fruit with the taste and aroma of fruits, such as strawberry and guava. Inside the green outer are tiny, edible seeds inside a jelly-like centre, full of vitamin C. The fruit can be eaten fresh or they can be used in fruit salads, jams or jellies.
To produce the best results, prune the tree back in winter to a single trunk. This will promote new fruiting branches close to the trunk. It will also benefit from rich compost and thick mulch.
