Thanks for your replies! Here, in England, I've never heard of a 'walking'
onion so exactly what does it do - how does it walk???? Could be a bit
unnerving to see a herd (flock? gaggle? pride? school?) of these crossing
the road when you're driving along minding your own business!!! Only
kidding! But it brought so ,many amusing pictures into my mind!!!
We are growing tree-onions, which produces, firstly, a strong stem and at
the top of that a cluster of small bulbs. These appear green initially but
then turn brownish-red. They grow to about the size of a small gooseberry.
The onions also grow stems with proper onion flowers which turn to seed.
But you probably knew all that anyway!!
I will grow my own onions from seed next year where I have a more varieties
to choose from. What started me on this idea was that I ran short of onions
from the set so had to but small onion seedlings, rather as James said, and
I wanted to try it,
My regards to all and thank you again!
