I've been growing Pinguicula lusitanica for about 2 years. I don't have so many butterworts as I am not good at cultivating the species. But P. lusitanica is not so difficult to grow even for me! Fruiting the seeds, they tend to wither. So I sow the seeds on a year basis.
There seem to be regional variations in colour of their flowers. So it would be interesting if correcting them in different locations.
