I don't think there's a thread about Pinguicula 'Tina'. I'ts a plant that can sometimes be found in garden centres here. I bought mine years ago, before 1916 (the earliest photo in my files). I separated new shoots a couple of times since and gave them to people who lost them. I can't understand why, I think it's one of the easiest carnivorous plants to grow. I never add fertilizer to mine, and bring it inside when the temperatures go below 5-10° C at night. (Dates in the name of the files, ex : ...160924... = 24th September 2016)
Wow. I see from Pinguicula - Wikipedia that it's the sticky glandular leaves that "lure, trap, and digest insects in order to supplement the poor mineral nutrition they obtain from the environment". That explains what's clearly shown in your fourth photo.
The flashy green leaves are clean in winter, when I bring it inside. They prefer small insects. And they don't fancy spiders, but are indifferent to cobwebs... ;0)
This looks like a good plant to have in the kitchen during the summer fruit fly season; so, I took a chance and bought 10 seeds of Pinguicula grandiflora from India (through Amazon.ca) for under $15, including shipping. I found some Pinguicula 'Tina' plants at a Vancouver Island online site, but they were significantly more expensive. AlainK, I assume that you bought a plant in 2016 and don't have experience growing it from seeds.
Probably, yes, but I bought one years ago and couldn't keep it. Pinguicula is much easier to keep alive here.
