I really enjoy growing onions from seed. It never ceases to amaze me how something that looks like a small, black grain of sand, can become something that is so savory. Usually, less than half the onion seeds I plant actually sprout, but once they get started, they're one of the easiest vegetables to cultivate. Attacks from insects are rare and even squirrels leave them alone. Give them water and a nutrient filled environment using compost or fertilizer rich in phosphorous(10-20-10) and they'll be just fine in the ground or in containers. And as far as the flavor of fresh onions is concerned, well, try growing your own and see what your tastebuds think.
