Small to medium-seized trees, with an attractive bushy, spherical to broadly conical growth habit with branches growing close to the ground. Fast-growing when young, growing up to 1.3 m a year and are beautiful in flower. A keurboom is the perfect tree for the new, bare garden because it grows so fast it will take only two or three years before it will be creating shade, or a screen, and filtering the wind. It is also one of the best species to use as a pioneer in the first stage in the succession to forest. It is happy to grow out in the open, grows fast and quickly and creates the shade that the slower-growing, more permanent trees need to grow in.
