You can normally buy frozen ones at this time of year. I suggest he is a trio of months or so too soon for fresh ones. I also have a packet of the Hodmedods dried ones got them in a local garden centre with an upmarket food department.
They are popular in Egypt, which is odd since they do not grow well there.
What form is your OH looking for.
I am certainly growing them, they first batch have a tiny green shoot and the overwinter ones are just beginning to perk up.
