Freylinia crispa is grown easily from cuttings. Take soft wood to semi-mature, short cuttings in autumn, spring or summer. These cuttings can be treated with a rooting hormone to help stimulate rooting. They will root within a month. Once the cuttings have rooted, place them in a slightly shaded area to harden off for three weeks before potting. Pot in a well-drained soil mix and place under a shade net until ready for planting. Propagation from seed has not yet been tried.

The Kouga bell-bush is an ideal plant for any fynbos garden and will make an excellent water-wise garden plant in the winter-rainfall region. It will grow particularly well in well-drained loamy soils and will do well in a warm sunny spot or a lightly shaded area in your garden. The plant grows tall and vigorously so it can be planted as a screen to hide any structures or walls and can also be planted at the back of a bed with smaller shrubs and herbaceous perennials growing in front of it. Regular pruning will keep the bush nice and tidy. The bright purple flowers attract birds to the bush and it is ideal for attracting birds to the garden.
