I have grown garlic for the past couple years, using my extra grocery store bulbs. Even so, the flavor and texture of what comes from my own garden soil are way better than the store bulbs.
This year I took the next step and purchased some "seed" garlic. This garlic is specially produced to plant. I chose a stiffneck variety called 'Music', 2 packages with three bulbs in a package. I got about 30 cloves (check out how nice and big the cloves are!) and planted them in a prepared raised bed.
The cost was about $1 per clove, so my experiment is pricey, but hopefully the results will be worth it.
