That is really cool. I have one doing almost the same thing. It was a phal I rescued just for an experiment. It was a very healthy plant with great roots but unfortunately it had sent up two spikes from the very center which means eventual death to the plant. I bought it because I loved the color and form of the flowers and hoped that it would produce a keiki. It started with a bud swelling that at first I thought was a spike. It grew about two inches and then developed a leaf. Now it appears that it is starting to develope a spike above the leaf. Will be interesting to watch and for only a $1 a neat learning experiment no matter what the result. The orginal plant remains very healthy and sending roots out like crazy. Keep us updated on yours. Got to love the oddities of nature.
