An elephant garlic bulb can weigh a pound, but they are usually rather smaller. The commercially grown ones are usually about 4" across: Garlicfarm.co.uk has a photo of one showing it to be about twice the diameter of a golf ball, which is itself 1.7" across. But they do two varieties, one bigger than the other. The ones I have grown (so far) have been rather smaller. I've been saving cloves, getting them in on time for once, and improving the soil so I hope to do better this year. Elephant garlic has a distinctly yellowish colour to the skin between the segments. But it isn't a spring planting garlic. It lasts far better than other garlic once harvested.

I can't find a garlic variety called "flavour", nor does that sound anything like what anyone here sells as a spring-planting garlic. But what you need is info on spring planting garlics, regardless of its variety name. What I found is plant them Feb-Mar, so get it in quick. A problem with late planting is that they do need a chill, and I have seen a description of commercial growers putting their spring garlic cloves in the fridge for a bit before planting.

If you find you get a crop of one-clove garlics, best just to replant them in October (or leave them in) for next year.
