Not only the flower is charming, the foliage of Smithiantha is also lovely. Benefited by the current cool weather in northern Taiwan, these plants are happy to expedite their growth. I just use liquid fertilizer twice a month, and it seems it's enough.
Doing a F1 hybrid is usually the first step to begin a hybrid work, and sometimes it does get classic result like Sinningia Amizade. F1 hybrid shows the combination of parents in the first place, so ... conservative speaking, if the parents are not poles apart, the result will be within two species. But a experimental trial with poles apart is a must, because a highlight may happen from such collision and that's why the hybridization keep progressing. In short, don't stay at comfort zone for always. :-)
The Kohleria is getting more popular and many growers are interested in the hybridization work because more pollen parents are available after efforts of some local hybridizers over years.
The main stream of developing new Kohleria varieties is to get big and multiple blooms on a compact plant. This is a current that will never fade away. Other than this gorgeous target, properly the idyllic ideas such like foliage variegation and miniature size of Kohleria will enrich the appearance of creating modern Kohleria.
So ... let's wait and see , good luck for everyone.
