The Cannonball tree is cultivated all around the world for its fragrant flowers and ‘cannonball’ fruit. In India, Sri Lanka and Southeast Asia it has many religious and cultural significances. The Cannonball tree was named after enormous fruit-like nuts which are shaped like cannonballs, and when they fall, one can hear sounds like a cannon firing. In Guyana, cannonball trees are a spectacular sight to behold with their tall lumbering trunks, perfumed flowers and dangerous bomb-like fruits. Cannonball trees can be found in Brickdam, Georgetown and in the Botanical Gardens. The scientific name for this interesting plant is Couroupita guianensis.

The Cannonball tree is a deciduous, tall and soft-wooded plant. It can grow to heights of thirty-five 35 metres or one hundred and ten (110) feet. Its leaves grow in clusters at the ends of branches. They are usually eight (8 ) to thirty-one (31) centimetres long but can reach lengths of up to fifty-seven (57) centimetres. The flowers grow in racemes eighty (80) centimetres long. Sometimes the entire trunks of cannonball trees are covered with enormous racemes of these fragrant flowers growing up to ten (10) feet along tree trunks. Cannonball flowers are noted for their sweet smell, especially at night and early morning but are also distinctive in their features and red salmon colour. Flowers of the cannonball trees typically have six petals in colours from pink and red to yellow shades towards their tips. There are also two areas of stamens, a ring and an arrangement that is made into a hood. The fruits are rounded and surrounded by a woody shell and can reach diameters of up to twenty-five (25) centimetres. They are the wooden version of cannonballs, from which the cannonball tree is named. A tree can bear up about one hundred and fifty (150) fruits, each of which contains about sixty-five seeds while the larger ones can hold as many as five hundred and fifty seeds. Fruits take about one year to mature in most areas but can take as long as eighteen (18) months. The fruits of cannonball trees are edible but because of their unpleasant smell, most people do not eat them.

Stop by the St. Mary’s School in Brickdam, and observe the Cannonball Tree there, which is over one hundred (100) years old. Or, if you are visiting the Botanical Garden, make sure to find the sole Cannonball Tree still growing proudly there.
