|Sunspot Petit Pierre|
I tend to keep this plant in the conservatory rather than the greenhouse. It is a sport of Kleine Leibling, a very old variety from Germany and was certainly around in the 1890's. This also is a miniature with single bright pink flowers and small bright green leaves. It has sported several varieties and over the years I have grown some of them.
Kleine Leibling is a haploid - meaning it has only half the normal chromosomes. It does not set seed, therefore it cannot be hybridised by pollen. The only way to increase these plants is vegetatively, i.e. by taking cuttings. It does sport very freely. Indeed, I have heard of some people having this plant with all the different sports on the same plant. I would imagine it would have to be a very large plant, and would be a wondrous sight!
Here in the UK, Kleine Leibling is sometimes referred to as Petit Pierre. It is known in the USA as Kleine Leibling or Little Darling, the translation from German.
