Overall: I planted Allium sphaerocephalon 2 years ago in a pot where they have only morning sun except at the height of summer.We have had practically no sun and masses of rain this year but they have flowered for the first time. The bulbs were planted about 5cm (2") deep but have pushed up to just below the soil level over that time. I will move the bulbs to a sunnier bed next spring but I think my northern clay soil may be too damp for them over winter. I will grow on the small bulbs so in a pot as a back up.
