These plants come from the winter-rainfall region where temperatures can soar to well over 30°C in summer and drop below zero in winter, so they can be grown in most areas as long as the soil is well-drained and on the acid side, and they receive water during the winter months. They can tolerate a fair bit of cold and can even tolerate some frost. They will not, however, grow in areas which are hot and humid, as they are very prone to fungal problems under these conditions.

Seeds should be sown in autumn in a well-aerated and well-drained mixture and germinate best when there are alternating temperatures of around 4°C to10°C at night and 15°C to 20°C during the day. Soak the seeds in a 1% solution of hydrogen peroxide for 24 hours and then remove the softened outer membrane before sowing. A dusting of fungicide will be helpful to prevent disease problems. Cover the seed lightly with the soil mixture and place in a sunny, well-ventilated position. They can be pricked out into bags containing a sandy well-drained mixture in spring, once they have their first set of true leaves.

Cuttings can be taken in late summer or autumn and should be terminal or lateral shoots which should be growing in an erect position on the bush. Cuttings should be about 200-250 mm long, dipped in a growth hormone powder or solution and placed into a coarse, well-drained rooting medium in a mist bed with a bottom heat of 22°C-25°C. Good air movement is important to prevent fungal diseases. Rooting may take between 8 and 16 weeks and the plants should then be transplanted into bags, also containing a well-drained, sandy soil mixture and hardened off under 50% shadecloth for about a month before exposing them to full sunlight to further harden off.

When planted into the garden, the site should be sunny and well-drained and the plants should be well-mulched and watered regularly until established. A slow-release nitrogenous fertilizer which is low in phosphates but containing trace elements of Fe, Mg, Zn, Mn, and Cu is advantageous.

Fungal infections can be a problem when temperatures rise above 18°C and the relative humidity is above 75%. These conditions are probably the severest limiting factor as to where L. reflexum will grow well. Good air circulation is the best preventitive measure for fungal problems, but it may also be necessary, depending on weather conditions, to use a foliar fungicide as a preventative measure rather than as a curative one. Insect pests can be controlled with either a systemic or full cover spray developed for the particular pest.

Pruning is not necessary unless the bush needs to be shaped as this plant normally deadheads itself and the new branches then grow up from the position below the old flower head. If cutting for the vase, then it is advisable to make the cut into an area where there are still leaves and this will encourage branching. Cuts where there are no leaves will simply cause die-back of the remaining portion of the branch.
