I recently borrowed a book from the Mt Coot-tha Botanic Gardens library called “Five Decades with Tropical Fruit – A Personal Journey” by William Whitman. It’s about his introductions of new fruit into America. He confirms what I have mentioned in past newsletters that “vegetative propagation by air-layering and grafting from superior fruiting trees is recommended as trees grown from seed can fail to fruit or produce light crops of inferior quality. Vegetatively propagated trees can be expected to bear in the fourth or fifth year after being planted out.” Do visit the Botanic Gardens Library in Brisbane – they have a wonderous collection of horticultural books.

They are in the same family as Abiu. You don’t get a lot out of them and if you don’t eat near the skin, it’s quite pleasant. Don’t eat them too green or too ripe. Don’t grow the ungrafted varieties as the crop is unreliable. Ref: Bob Brinsmead – Tropical Fruit World
