I believe the plant that Jane found to be invasive and she shared with me is not A. membranaceum which is a lovely Allium that dwindled for me over the years alas and is now gone, but Allium amplectens. Since that one is found over a broad range of habitats and amounts of rainfall in winter, it probably depends on where you live whether or not it would be invasive and also on what clone you have. I don't think I'd do well with seed of it from dry winter areas. I've have really poor luck growing Alliums in the ground although this year of abundant rainfall some of the Allium unifolium I've planted out over the years are in flower. I remember seeing one in Southern California at Rancho Santa Ana that was covering a large swatch of ground and in flower, but it never made it in my ground. And in containers over the years many other California species I have grown have gradually disappeared (except for Allium unifolium which is native to where I live) and Allium amplectens which has increased in containers. I actually like A. amplectens because of it reliability. Perhaps I need to try again to plant it out and see if it survives. I would be happy if it increased in the ground, but given my previous experience I would also be surprised.
