Allium issues!

Despite a long gardening history I have never grown alliums but this year acquired a fair old mixed bag from an online supplier. I potted them up first in pots, about two weeks ago, and was stunned to see some coming through yesterday. This seems early? Should I leave them or what. The original plan was to plant out early next year when they appeared. They are currently outside so slowing them up wouldnt be easy. Do I just hope for colder weather. Have I planted too soon?

 

I would leave them to look after themselves, leave them outside in their pots. Quite a few Alliums flower at the end of their growing season, so flowers appear as the leaves begin to disappear.
Leaves appear overwinter or early spring.
Watch out for Allium sphaerocephalon (drumstick onion) I found it to be a bit of a thug, although quite pretty. Probably best left in pots. As it bulks up quite nicely you often get quite a few in a mixed pack of alliums.

 

They don't care if its winter or summer. They start to grow when conditions seem to be right. And if this happens to happen in October, so be it. They will halt their growth during winter times and resume once spring is around the corner. When frosts get to harsh, the tips of their leaves will start to get brown and fall off but this wont kill the plant. Just let it be and wait for the upcoming year.

 

Many thanks for the replies, very clear and helpful

 

That was another one that got turfed out, however Allium tripedale (nectaroscordum) is a far better behaved relative, slightly shorter and more delicate flowers are less droopy, so I now grow this one.
