When you observe a plant, leaves are the first thing that comes to your mind. Still, another essential part of the plant anatomy is the bract, an overlooked feature that plays a crucial role in plant functions. Bracts are modified leaves found near the plant’s reproductive structures, such as flowers and cones, often overlooked in favor of other prominent parts of a plant, like flowers or leaves.
Bracts come in various shapes, sizes, and colors, depending on the plants they are part of, and can be single or in clusters. The poinsettia plant is a classic example of plants with brightly colored bracts, which is often mistaken for flowers. Bracts are also present in plants such as the hydrangea, where they are instrumental in attracting pollinators, while the brightly colored ones in Bougainvillea help draw attention to the plant’s underlying flowers.
One of the most important functions of bracts is to protect the flower while it develops. In this way, bracts act as a kind of barrier, offering support and protection to the plant’s reproductive structure from damage caused by insects or extreme weather conditions. Bracts also serve as a landing pad for pollinators, leading them directly towards the flower, and aiding in the pollination process.
The bract also plays an essential role in the reproductive structure of some plants. For instance, the African violet develops its flowers from the side of the bract where it also receives nutrients. The bract of the pineapple plant similarly supports the flowering structure, and when the fruit begins to develop, the bract becomes an integral part of the fruit.
While bracts are essential to many plants’ health and reproductive success, they often go unnoticed by most folks. Next time you see a beautiful flower, take a closer look, and you might be surprised to find that the plant’s real beauty lies in its unsung hero, the bract.
