I like allium flowers, and next year I am going to buy some with the big purple globes and plant them all over the garden.
The flower above is one of three that I believe come from garlic that was planted my first summer in the house. As the only available garden at that time was under the tree in the front garden, I planted everything there depite the ground being full of roots and very hard. Eight years later and I have interesting flowers from some of the unharvested garlic. There is no point trying to move them as I have plenty of garlic for eating in my raised bed garden in the back.
