I received a flower bouquets on May and the plant that came with the flowers has been alive for following 3 months (I think it's slowly dying). I noticed some unusual growth on the back of leaf and had no idea what it was. About 3 leaves are showing the same growth and yesterday one fell off but it was green n round, this morning I noticed how this thing 'bloomed' on water :( I've been researching and all I can come up with it is either some kind of seed, protection, or bugs?? Any idea?
Without seeing the plant, I can't really tell for sure, but it looks like a bud has formed on the lower surface of that leaf. It may produce a small plant similar to the larger one. Sometimes we call these adventitious buds, and they are unusual. It does not look like an insect to me.
