Allium flower head size
I planted Allium Beau Regard and Globemaster in Autumn 2004. These are my first Alliums and so I'm not sure what to expect as far as flower size.
They have come up fine and have perfect shaped full flowers, but they are only about 6" diameter. I thought they were supposed to reach 8-10".
Do the flower heads get larger in subsequent years?
Do you leave the bulbs in the ground after flowering or are they left in permanently?
