This is a carnivorous plant. Insects become trapped in the pitcher-like leaves. The insects are then digested, and the nutrients used by the plants.
So in an early post from last summer, I told the story (here) of my idea of getting wasps in the solarium to eat the aphids. I had also gotten a northern pitcher plant to help with the aphid problem.
Today I wondered why the leaves that ate the wasps died. I snipped off the largest one. (I'm thinking it's not coming back to life this summer.)
|See? It's still green at the bottom.
|OHHH! Check out all those bugs!!!
|I can even see lady bugs in there!!!
|AH HA!!! There is a clog! Can you see that wasp??? The head is way down there not attached to the body. And that's where the green part starts! Amazing. Is there Metamucile for Pitcher Plants? :-)
