Hi Marguerite, I sure hope the 1015Y is suitable for your area. It is a wonderful onion for eating raw, like the onion sandwich you mentioned. Add a slice of fresh garden tomato, knock your socks off. They also make great onion rings. One draw back of short day onions is that they do not store as long as the long day varieties. The sweetness of the onion is related to water content. The more water content the sweeter the onion and the shorter storage time. I'm a freak for onions. The 1015 Y's are the best that my dad, grandmother or myself have grown. They get big too! Dad and I were competing for bragging rights last year. He won. He had some bigger than softballs. Mine were only a little smaller. We have never had any problems with frost damage to the 1015Y. We plant the little transplants in Jan. They always have to go through several hard freezes. The name 1015Y comes from the planting date if you plant from seeds. Oct. 15th, yellow onion = 1015Y. Happy Gardening, Allen Bastrop Co., SE Central Tx. Zone 8
