I like them in a huge bunch like this. I also let them seed out in some of my other gardens. They are even growing in a garden that is mostly shade! So they are versatile as well. Plus all the little extra plants that I thin out can be eaten. Yummy!
These actually bloomed about a month ago. Oops. I can't always be on top of things. That's why I love plants that need no special care- I'll forget to do it. These onions need nothing, except maybe a little staking when they get really tall and the flowers are heavy. These ones did just fine this year until a big storm bent some of them over. And really, I never stake them. I just let them bend where ever they want.
