Relax. The elephant garlic is different than regular garlic. It will have that beautiful flower for you to enjoy and it will still put on a nice bulb for you to harvest later. Some say to cut the flowers for a larger bulb, but my own experiments say its a waste of time to do that. I couldn't see any significant difference in the bulb size. Just enjoy the bloom.
