Early last spring ( 2015) I was ordering a couple of hard to find Darlingtonia ( If they are actually as described) and I decided to add Pinguicula vulgaris seed to the order as I hadn't grown the species for many years. Nothing at all happened in the pot last year except for the customary sprouting of non-carnivorous bog greenery. The same result this spring and I needed the room the pot was taking up so it was going to be discarded on the garden. A quick check before the ol' heave ho and there were these mini-pings waving at me.
This goes to prove once again that once a pot is designated devoid of meaningful life a moratorium should be declared for a period of about 4 years.
