Dear Jennifer, After seeing all those wonderful images from Mark McDonough of masses of Alliums in the ground, it may seem like the only way to grow them. The California species are very easy to grow in containers and I have found them to do better for me that way in fact than in the ground. Most of them don't require deep pots either. You can see pictures of many of the ones I grow on: http://pacificbulbsociety.org/pbswiki/index.php/… You may want to wait until you know where you are going to live. There are so many of them that you may want to pick which ones to grow after you know your climate. I have a couple pots of Alliums given to me from my friend Jana out of one of the bins at the store that I have not even repotted since they hardly go dormant and they have survived and bloomed that way for a number of years.
