I can't wait to see that first hand. I've not had that happen in any of my plants yet...
My venus fly trap site
I wish I would have posted it when my conversation with the grower was more fresh in my memory. However I believe he said this tends to happen when they bloom in cooler conditions for him. He had at least 5 plants growing like this. The plant does not continue to respond like this, and may go in and out of "tree phase" between the years.
While I was, "omg fun!" the grower was more, pa say... "ah yes, they tend to do that from time to time."
Neato! I would love to have that happen to me.
Perhaps if people continuously interbreed all of the plants that show this trait, someday we'll have one that does it regularly.
Andy, Owner of the forum had a dentate or two that did this.
That is AWESOME!!!!
