Leucosidea sericea is a frost-resistant evergreen tree, which makes it an ideal species to use to protect less frost-hardy plants during winter.  Because it is fast-growing, it can be used to establish an evergreen canopy relatively quickly, while slower-growing trees can be used around it and ultimately take its place once they have developed sufficiently.  The tree can also be used to provide shade in summer, if low branches are trimmed off.  The ouhout is a dense plant that can be used to provide a screen against noise, objectionable views, and wind.  The tree can be very successfully utilised near water sources such as rivers and dams, since it enjoys living in damp areas.  It possesses a slightly weatherbeaten and untidy general appearance, due to its gnarled, flaking trunk and irregular form, and these qualities can be utilised well when trying to create a naturalistic indigenous African-style garden. Due to the concentration of silver hairs on the leaf edges, the tree possesses a silvery sheen in the sunlight.  

The ouhout is also suitable for use as a bonsai tree.

Leucosidea sericea is propagated easily and quickly from either seed or cuttings.  Seeds should be sown in good seedling medium and kept moist.  Seedlings can often be found underneath parent plants, and may be carefully removed and planted in nursery bags filled with a suitable soil medium.
