The life cycle of the Mesquite is the same as any other angiosperm starting with the production of flower which in turn creates an egg in each ovule. Once the egg is in existence pollination occurs thanks to pollinating creatures such as bees and butterflies and because of stamen and pistils, which allows self-pollination. After pollination, fertilization generally occurs, producing an embryo within a developing seed. A fruit then encloses the seed for protection, the fruit, which attracts animals, is then eaten and those seeds are dispersed by domestic and wild creatures, Then the dispersed seeds begin to grow into a new plant. This is shown in the diagram below.
The life span of this tree is, if undisturbed, between 172 years and 217 years. This life span is pretty moderate for trees. In the span of these years they can grow up to 25-30 feet tall and 30-45 feet wide.
