Plant Profile: Abiu

Abiu was one of the first unusual fruits I ever ran into after moving to the Big Island, so it holds a soft spot for me even though it’s honestly a bit of a mixed bag.

The Basics

Abiu, Pouteria caimito, is native to the western Amazon basin of South America, in the same family as eggfruit and sapodilla.

Origin and Habitat

In Brazil it’s apparently common enough to find growing near doorways and on empty lots, which says something about how easy going it is once it’s established somewhere warm and humid. It’s spread well beyond South America since then too, and shows up scattered through home gardens in Florida, Southeast Asia, and here in Hawaiʻi, usually as a curiosity rather than a commercial crop.

What It Looks Like

A medium sized tree, densely branched with a fairly neat, conical canopy, which honestly makes it a decent looking ornamental even before it starts fruiting. Like a lot of its relatives it has a milky latex sap running through the leaves, bark, and fruit skin, and produces smooth, round to oval yellow fruit. The one currently in our ground came from my friend Mary.

Uses and Flavor

Abiu can taste like plain sugary water if you get a mediocre one, but a good one reminds me of the caramel part of a flan, which I really like. The flesh is this translucent, jelly like stuff you can practically scoop out with a spoon. A mature tree can throw hundreds of fruits a year, which is a lot considering how few people around here have even heard of it. Worth clearing up too, since it trips people up constantly, abiu is not the same thing as star apple, which goes by the very similar sounding name caimito in some countries and is actually a different genus entirely, Chrysophyllum instead of Pouteria. Two completely different fruits sharing overlapping names across different parts of Latin America.

Growing It Here

This tree was already established before I started this project back in 2021, and it’s kept doing its own thing since, producing fruit sporadically rather than in one big flush, which suits me fine given how many hundreds of fruits a mature abiu can drop at once. I keep it topped below 20 feet so picking stays a hand job instead of a ladder operation. Its quieter neighbor down the row, abiurana, is still waiting on its first fruit, and a little further out the same Sapotaceae family shows up again in our mamey sapote.

Pests and Diseases to Watch For

Relatively few serious problems here. Fruit flies will go after ripe fruit if it’s left too long, same as most soft tropical fruit, and mealybugs occasionally show up on new growth, but neither has been a major issue for us so far, and I haven’t had to spray for anything on this tree yet.

Kenta’s Take

One person’s dooryard tree is another person’s exotic curiosity, I guess. Ours has settled into a steady, sporadic rhythm at this point, still no real schedule to it, but when it hits, it really hits. It was one of the very first things that made me realize just how much unusual, delicious fruit is out there that never makes it into a regular grocery store, which is honestly a big part of why I got into all this planting in the first place.
