Gymnosporia buxifolia can be used as a barrier plant, boundary plant, hedge or screening plant, as well as a bonsai. Prune to shape, and to increase branching, and trim to create a dense, impenetrable hedge. It is frost hardy and drought resistant and is a tough pioneer species, useful on exposed sites and to create shade for slower-growing trees. It is also suitable for coastal gardens. It is ideal for a wildlife-friendly garden or in a natural garden, as it brings wildlife into the garden, attracting flies, bees, butterflies and other insects, that further attract birds. The smell of the flowers can be quite unpleasant and overpowering, so do not plant it too close to your house; it flowers (and smells) for a few weeks to a month in the year.

Gymnosporia buxifolia should be planted in prepared holes with some compost and bonemeal added, and mulched well. Water regularly until well established, then reduce water until the plant is thoroughly hardened and water wise. Unless you require fast growth, this shrub will need no more attention, other than an occasional pruning if necessary; it is a low-maintenance plant.

Collect the seeds from the capsules after they split open. Sow seeds immediately, or store in a cool dry place and sow in spring or early summer.
