I have a few Pinguicula Laueana 'CP2' x Emarginata available grown under LEDs in my greenhouse. These pings are so fascinating and do their job well catching mosquitoes and gnats regularly. They have white and purple slimey leaves that catch and absorb/digest any small insect that gets stuck on their leaves. If you have gnat problems, this is the plant for you! 🐜🪰🌸
