My husband loves these plants/flowers I am very new to gardening and thought I would surprise him and plant 5 new alliums for the first 2 months they were beautiful, in the last 2 weeks 3/4 of them are lying flat on the grown but are still producing new flowers. I watched the sun and they do receive morning sun from the other side for several hours every morning so I don't think they are tracking the sun like sunflowers do. Several of our neighbors have these plants and they are planted in the shade the best I can tell and theirs are pointed straight up. If anyone can give me any suggestions I would really appreciate it. Again I am very new at this and don't have a clue what to do. The leaves are very green and don't show any sign of yellowing, dark spots or holes if that helps.

Thanks again for any help you can provide!!!
