Aeollanthus rehmannii is a sun loving plant and it can also withstand some shade, but for best performance it is advised to plant it in an area that receives six hours of direct sunlight each day. The plant may grow lanky and produce fewer flowers if it does not get enough sunshine. It grows well in temperatures between 15-27°C. It need to be protected in winter because it cannot withstand freezing temperatures. Move the plant indoors or to a warm spot before frost arrives if it is grown in a container. Plants require well-drained soil with a slightly acidic to neutral pH. Although it may grow in a variety of soil types, it prefers sandy fertile soil. To enhance the structure of the soil and supply nutrients, incorporate organic matter into the soil prior to planting. Regular watering is necessary, but as the plant is prone to root rot it should not be over-watered or left to stand in water. This is a lovely plant that can give any garden some colour and texture.

There are several ways to propagate this plant:

Seed propagation is the most popular technique for Aeollanthus rehmannii. When the plant has generated mature seed pods, it is advised to gather the seeds when they are fresh. Before planting, the seeds need to be dried and kept in a cool, dry location. To break whatever dormancy the seeds may have, immerse them in water for a full day before planting. After that the seeds are planted in pots or seed trays filled with a mixture of compost and sandy soil. It is important to keep the seedlings in a warm, well-lit place and to water them frequently.

Propagation by cuttings is another easy method of propagating Aeollanthus rehmannii. It is best to take roughly 10 cm long cuttings from semi-hardwood stems in spring or early summer. After dipping these cuttings in rooting hormone, they ought to be planted in a mixture of sand and compost. It is important to keep the cuttings moist and out of direct sunshine. In roughly four weeks, rooting should take place.

Propagation by division can be accomplished when a plant has grown too big for its pot or setting, it can be carefully dug up and divided. Gently shake the uprooted plant free from soil, or wash the roots. Select sections of the root that have multiple strong stems and cut them free from the mother plant. These separated pieces need to be replanted immediately in a sand and compost soil mixture, watered well and placed in a warm, well-lit location. Water frequently until the transplanted pieces are established.  

Using any of these techniques to propagate Aeollanthus rehmannii is comparatively simple and can produce a strong, healthy plant. It is crucial to remember that the greatest outcomes and the highest success rate are guaranteed when the plant is propagated correctly.
