Selago corymbosa is easy to grow. Propagate plants by making tip or stem cuttings. Cut below a node and remove the lower third of the foliage from the cutting. Dip the cutting in a rooting hormone and place it in a well-drained medium consisting of equal parts of milled bark and perlite. Place the tray of cuttings in a mist-unit on a heated bench. Within a month, cuttings should show signs of rooting.

Once the cuttings have rooted, remove them from the mist-unit and place them in a semi-shaded area, where they can grow for 1-2 weeks, in order to allow them time to harden-off from the growing conditions in the mist-unit. Water the rooted cuttings once or twice a day, depending on how quickly the medium dries out. Once hardened off, the rooted cuttings can be potted up in  to a well-drained potting medium and placed in a sunny position. When the plants have grown sufficiently, they can be planted into the garden.

Selago corymbosa is great for creating a soft effect when tucking it in between other plants in full sun or semi-shade. It can survive dry conditions once established but can also tolerate a slightly damp area. It prefers well-drained sandy or loamy soils that are slightly acidic to neutral. After flowering, cut the plants back to encourage new growth and to keep them looking neat.
