I can't imagine that any stalk/flower combo will not topple this precariously large amaryllis. Niece Kristy got it for me for Christmas – so it's not even two months old. It appears to be growing to ginormous proportions. I'll have to either place it on the floor, or raise the ceilings, when the flower stalk appears. Never having grown one before, I don't know what to expect. If size matters, then it'll be impressive.
