Growing Garlic

I found many interesting things in this article but the three most interesting things I found were that two main types of garlic and one type that looks like garlic but has no garlic flavour which is called 'elephant garlic'. Another thing is that a deep, very fertile and well drained soil is ideal for growing garlic. Lastly, the cold of winter is needed for the side buds to grow that will eventually change and swell to become cloves. One thing I want to look for next time I am in the garden is to see how garlic looks when it's growing and what it looks like when it is ready to harvest. One question I have is how difficult if garlic to grow compared to other vegetables?
