Why does Diamond tree Carob bloom on old wood?
💎 Why does Diamond tree Carob bloom on old wood?
No petals, no familiar blossoms - just mysterious reddish clusters growing from old branches. And a surprising connection to diamonds!
I noticed something unusual in the garden today. Strange reddish flower clusters were emerging directly from old woody branches. What on Earth was flowering like that?
At first, I couldn't recognize it. Then it hit me - our Carob Tree (Ceratonia siliqua) was finally blooming!
And what unusual flowers they are!
Unlike most familiar flowering trees, Carob produces clusters of tiny, petal-free flowers directly on mature branches and sometimes even the trunk!
💡This unusual habit is called ramiflory (flowering on old branches) or cauliflory (flowering on the trunk) - and can bee seen also on trees like Jaboticaba, Mamey, Hug Plum, Cacao.
Instead of colorful petals, the flowers display prominent stamens or other reproductive structures, often in reddish, orange, or yellowish clusters. Some even have a strong, musky fragrance!
Here's another surprise. Carob trees can be male, female, or hermaphroditic. Male flowers produce pollen, female flowers develop into pods after successful pollination, and hermaphroditic flowers contain both reproductive parts. So, not every flowering Carob Tree will produce fruit! If you're growing seedlings, their sex may remain a mystery until they bloom.
The famous Carob pods eventually turn dark brown and become naturally sweet. Their dried pulp is ground into carob powder, a caffeine-free chocolate alternative!🍫
Ancient merchants used those hard seeds as reference weights for precious gemstones. That's where the word CARAT comes from!
Read our previous story: The tree that gave diamonds their "carats"
Native to the Mediterranean, Carob is a beautiful, long-lived evergreen that loves sunshine and heat. Once established, it's remarkably drought tolerant and thrives in well-drained soil. Mature trees can handle brief light freezes, although young plants need protection.
Carob can live for centuries, providing shade, unusual flowers, and potentially sweet edible pods for generations.
An ancient Mediterranean treasure, now growing at Top Tropicals! Carob is an uncommon find in Florida nurseries, and we have only a few plants available. Get yours before they're gone! Bring home your own living piece of history.

💎 Will these strange flowers become fruit?

💎 Diamonds for seeds?
