I have been planting Park Seed's Granex onion seeds for 4 years now and they are always good germinators, healthy plants, and great onions. I plant the seeds in early November (I'm in Los Angeles), and can start harvesting good-sized flat globes by late April through June. I store the dozens of them in my shed as it is usually dry, and they don't mind the heat of summer either. They are great raw, and also make excellent onion rings.
