Ruttya fruticosa is an attractive, fast growing and easily grown ornamental plant. It is best suited in tropical and sub-tropical climates. This plant species is known to be evergreen in warm areas but in temperate climates, particularly in cold periods, it behaves as semi–deciduous, dropping its leaves which will resprout in spring. This plant species grows best in well–drained, slightly acidic soil with little bit of added compost,  in rocky areas, in full sun or partly shaded. It can tolerate short periods of drought and is semi-hardy to frost. It should be watered twice per week and fertilized with an organic fertilizer twice per year. Pruning should be done in late winter, after flowering, to encourage new growth and in summer, to give a more compact shape and to keep it tidy. Its roots system is not aggressive, it can be planted near paving or foundations.

This beautiful shrub is a very good choice in smaller gardens. It is suitable to use for screening, as an informal hedge, as a windbreaker and can be planted in a container. It is also specifically planted in the garden to attract birds, bees and butterflies. Ruttya fruticosa looks good when planted together with Plumbago auriculata, the beautiful blue blooms make a pleasing colour combination with its reddish orange flowers.

This plant species is most likely to be infected by leaf-yellowing diseases which is caused by insufficient of essential nutrients, caused by both overwatering and underwatering. The leaves are subjected to attack by Aphid and Whitefly which feed on the leaves. Pesticides should be used to control the pests.

The beautiful jammy mouth plant can be propagated by stem cuttings or seeds. Cuttings should be placed in a mist house on raised beds with bottom-heating cables. Washed river sand is the best medium for growing Ruttya fruticosa cuttings. Propagate cuttings in spring. Take cuttings in the morning, use a sharp knife or secateur to reduce injury to the parent plant, place the cuttings in a plastic bag immediately after harvesting to avoid water loss, remove the lower leaves but leave the top two or three, cut stems just below a bud, apply rooting hormone to the bottom end of the cutting, use a dibber stick to make holes in the soil medium, the holes should be larger than the cuttings so that the rooting hormone is not rubbed off when the cutting is placed in the medium. Stick the cutting in to the growth media, gently press the medium around the cutting. Water the cuttings.

Ruttya fruticosa seeds should be sown in spring. Seeds should be removed from the capsule. Prepare the soil by mixing 1 part of washed river sand with 3 parts of potting soil, fill the seed tray with the growing media and firm it down, space the seeds evenly, cover the seeds with a thin layer of growth medium. Water the seed tray thoroughly and place the seed tray in a germination house. Germination will start after 3 weeks. Seedlings should be pricked out and transplanted when they are 5-8 cm tall and have 2 true leaves. Seedlings should be hardened off for 2 weeks. This plant species can be planted in the garden when it is 1 m tall.
