I have several different size variations of Pinguicula lutea. I have a smaller type that hales from Hampstead, North Carolina, USA and another of unknown location detail. The unknown is the larger. The plant nearly fills a 6 inch (15 cm) diameter pot, the flower stalk can grow more than 12 inches (30 cm) high, and the flower is a rich dark yellow and presents facing the horizon and is 3-4 times larger than the Hempstead flower. The Hampstead plants rosettes are only about 3 inches (7.5 cm) in diameter and the flower stalk is only about 5-6 inches (12.5-15 cm) high. The flowers present facing up, are thin petaled and pale compared to the unknown larger plants flowers. Perhaps this is a factor of autopolyploidy, but I have never done a chromosome count to verify. They each had a solitary fall flower happen simultaneously and I was able to transfer pollen from each to the other and seed pods are developing. Earlier I was able to self the larger variety and have seedlings growing from those now. This is the Hampstead plants first flower. I am excited to see how these do in the long term.
Has anyone else noticed anything like this with any of their Pinguicula?
Here is a picture of a flower from the larger type:
