Scapes are the plants "seeds" they grow above ground at the top of a mature plant
This picture doesnt show it but each pod is filled with new tiny bulbs. You can plant them, mine are growning great, but they take a couple years to mature.
I planted cloves from a bag of garlic I bought at the store...when separated, it came to 220 cloves of garlic!!! Don't know where I'm going to plant all this garlic but I'm certainly going to try and stick it in anywhere I can. What I can't plant, I'll dehydrate and grind into garlic powder.
