This stachys is used as a perennial for summer displays. Its low, lush foliage can be used as a groundcover in moist, open beds and can create an attractive cascade of foliage in deep, well-watered containers. 

Young plants are planted out at the end of spring. Stachys aethiopica is easily combined with most flowering perennials and also give good contrast with Fynbos such as Restionaceae, Proteaceae and Ericaceae.

The fast-growing plants can get untidy and after each growth period in summer, plants can be pruned back to retain shape and encourage new growth. From time to time, it will be beneficial to replant propagated plants, to improve the display.

Young plants are easy to propagate from seed or cuttings.

Sow seeds late spring and early summer into a general potting soil mix. Seedlings germinate quickly and seedlings can be transplanted into well-drained, potting soil, once the first pair of true leaves appear.

Take tip cuttings in spring and summer. Cuttings must be without a terminal flowering bud. Place in rooting medium, 50% fine milled bark and 50% polystyrene (perlite, vermiculite, river sand and peat are alternatives). Place under mist or enclose in a plastic bag, to retain humidity. Keep warm, but out of direct sunlight and cuttings should root in 2–4 weeks.

If the planting is established, rooted runners of overgrown plant material can be cut back and replanted.

Because of the hairy and aromatic leaves, the plants do not have any major pest, although mealy bug can settle down near the base of the plant stems and leaves.

Stachys aethiopica tolerates a range of growth environments and soil types. It prefers a well-drained soil that is watered regularly. It will spread rapidly and flower in shade to full sun conditions. Flowering is consistent and improved with good garden cultural practices, like composting or mulching. It is water wise, but not fully drought tolerant. General garden fertilizing can be used to maintain plant health and growth vigor.
