Pinguicula 'Weser' is one of my favorite Pinguicula. Several years ago I received my first one in a trade. Since then, using conventional propagation techniques and a minimum amount of time I have produced many hundreds of divisions which I have sold and traded widely. Undoubtedly if I had more space and spent just a little more time I could easily have propagated my original Pinguicula 'Weser' into an enourmous quantity of plants, it is very prolific and vigorous.
I don't remember ever losing one to any kind of pest or disease, they tolerate a wide range of growing conditions, and they bloom freely and are self-compatible easily producing seed which grow to produce F2 generation plants. These, of course, are not Pinguicula 'Weser' but just Pinguicula 'Weser' x self.
If anyone is not yet growing Pinguicula I would highly recommend Pinguicula 'Weser' as a very nice plant to begin a journey into the growing of Pinguicula or just to round out a Carnivorous Plant collection.
