Pruning
Pruning the plant is not necessary, but it can promote consistent growth and flowering. It is advisable to prune after the flowering season to prevent cutting off new buds that may form in the same season. Only get rid of dead flowers, leaves, and branches. Make sure to sterilize your cutting tools before and after pruning to avoid fungal infections from spreading in the plant.
Propagation of Aptosimum lineare Marloth & Engl. var. randii (S.Moore) F.E.Weber
Aptosimum lineare Marloth & Engl. var. randii (S.Moore) F.E.Weber, commonly known as the Namaqualand copper, is a beautiful South African flowering plant that belongs to the family Plantaginaceae. It is a small, perennial herb with narrow, linear leaves and showy orange-red flowers. Propagation of this plant is relatively easy, and it can be propagated from seeds or cuttings.
Propagation from seeds
The most common method of propagating Aptosimum lineare Marloth & Engl. var. randii (S.Moore) F.E.Weber is from seeds. The seeds should be collected from mature plants in the autumn when the fruit capsules have dried and split open, revealing the small, black seeds inside. The seeds should be sown in a well-draining sandy soil mix, and lightly covered with soil.
The seeds should be kept moist, but not waterlogged, and placed in a sunny location that is protected from strong winds.

Once the seedlings have reached a good size, they can be transplanted into their final growing location.
Propagation from cuttings
Aptosimum lineare Marloth & Engl. var. randii (S.Moore) F.E.Weber can also be propagated from cuttings. Softwood cuttings should be taken from new growth in the spring or early summer. The cuttings should be approximately 5-10 cm in length and should be taken from the tips of healthy stems.
The leaves on the lower half of the cutting should be removed, leaving only a few leaves at the top. The cuttings should be inserted into a well-draining soil mix or peat moss and sand mix. The container should be covered with plastic to maintain humidity, and the cuttings should be kept in a warm, sunny location.
The cuttings should root within two to three weeks, and once they have developed a good root system, they can be transplanted into their final growing location.
Overall, Aptosimum lineare Marloth & Engl. var. randii (S.Moore) F.E.Weber is an easy plant to propagate, and with proper care, it can quickly establish itself and produce beautiful flowers year after year.
