What’s Blooming in Paradise: Macadamia Nut Tree (Macadamia ssp.)

By Staff | Jun 10, 2015

First Impression: Fuzzy, creamy flowers that remind me of slender bottle cleaners dripping from a petite tree. These flowers before the fruit are going to become everybody’s favorite snack. Who would have guessed this small tree months from now will have macadamia nuts ripening? Just gazing on upon the blooms may make you feel a little nutty, at the Botanical Gardens of the Sanibel Moorings.

Upon further investigation: The macadamia genus has approximately 10 species of trees. Many different cultivars of trees have been produced, which makes your choice either confusing or engaging. Luckily, it is a lovely tree even without the harvest, with a natural shape and smooth gray trunk. Slow growing, our tree is petite at about 24 feet tall but others can reach 35 feet high, of evergreen and dense with dark green leaves which are arranged in a whorl pattern. Fuzzy flowers are long sprays of creamy, tiny flowers in the shape of caterpillars.

The star of this tree is the nuts which develop after the flowers. Each flower stalk can produce up to 25 nuts. Patience, it takes seven months after the blooms for nuts to be edible. These very round edible nuts are encased in a hard dark green leathery husk. This husk splits open as it ripens and the nut falls to the ground. No need to pick them, they are ripe when they fall from the tree. Did you know the nut is reputed to be the hardest nut in the world? It requires at least three hundred pounds of weight per square inch to break the shell completely. Yummy, delicious, creamy, crunchy, buttery and sweet, the flavor reminds me of a very buttery brazil nut.

The macadamia nuts you purchase in the store have been processed. You may eat these unprocessed nuts fresh from your tree. Be sure to consume them within a month or less. First remove them from their husk and shell. Set them in the shade to dry out for about two weeks. Watch out, this is the time you’re nuts may end up in some ones else’s tummy. Approximately two weeks, you can eat them or toast them in the oven. It will take new trees approximately 4 to 6 years of age for them to start producing nuts. Besides being yummy, the oil is known to have amazing properties that can rejuvenate our largest organ, the skin. It’s loaded with natural anti-aging acids, which is always good to have around! Interesting trivia: Did you know that macadamia trees are not native to Hawaii? Years ago an Australian farmer brought his native tree to Hawaii and an entire industry emerged.
