I have a large green tiger lotus it has been sending off pups like crazy, I can see what I think could be a flower bud just forming in the centre . But what I'm puzzled on is there is a stem that is coming out of the main plant the diving into the substrate about 10cm away from the main plant. It has been there a while and I thought it was just a leaf that I have cut off, anyway to cut to the chase I had a bit of a dig around and it has a monster bulb on the other end of it maybe 20mm in diameter. it has no leaves or steams of its own but it does have roots. Is it another plant bulb? and will it get leaves? and how soon can I cut it off the main plant?
