You have a pretty Clivia in care. Visitors have noticed it and have expressed the wish to grow such a beautiful plant themselves. How can you fulfil such a wish?
The easiest way is to divide the existing plant, provided that the plant has produced the appropriate offspring. You should make sure that there are at least 2, preferably 3 pairs of leaves on the child. It is said that if this is not the case, the flowering of the child is jeopardised. I cannot confirm this from my own experience.
This division ensures that you get a 100% identical plant to the mother plant.
The next option is to sow ripe fruit. If berries have been formed through self-fertilisation or targeted pollination with pollen from other plants, ripe fruit can be harvested after 6 - 15 months, depending on the type of plant, and sown. It should be noted that not 100% of the mother plant's plants will develop. The rules of inheritance must be observed here. As it cannot be assumed that the private owners of the plants know the parent plants, the surprises will be all the greater as to what flowers usually appear after 4 - 5 years. It is certainly possible to grow special colour variations and flower shapes. However, you should not set your expectations too high as you will be all the more disappointed if they are not fulfilled. Without the appropriate knowledge, special colour variants can only be expected in exceptional cases. The dominant orange colours are the rule.
