Cannonball Tree

You’ve never seen fruits like these. Meet a member of the Brazil nut family in the Nutrien Garden of Life, right in our ENMAX Conservatory.

Fragrant flowers, grown directly from the… trunk?

The cannonball tree is flagelliflory, meaning that flowers form on the tree’s trunk, rather than growing alongside its leaves. A single cannonball tree can have more than 1000 flowers that give off a strong scent, particularly in the early evening and in the morning. True to its name, a cannonball tree grows fruit that resembles a cannonball, and they are about as tasty as one – while edible when ripe, the fruit has an unpleasant odour and is a sickly green-blue when it oxidizes, and so its primary use is medicinal.
