These bulbs came from my grandparents' old homeplace. They're both gone & I'd like to plant these. A friend of theirs dug these up & said they were garlic but they don't look like the garlic I'm used to seeing in stores. These were in north Louisiana & were prolific from what I remember my grandfather saying. (1) ARE these garlic? (2) Any way to find out what kind they are? (3) When & how do I plant? ALL help & advice MUCH appreciated!!!!
