I know that I can buy seeds (not talking about onion sets), but I've got two
onions that have produced nice 3" flower heads that seem to still be
blooming. What I'm wondering is how long should the flower heads be kept for
the seed to viable? I mean should the flowers all die and the head change
color or what? The flowers right now are such a light green as to almost be
blue.
TIA

Until the pods are dry.

I get chives coming back from seeds every year and they spread from the
pots to the ground because I did not gather all the seeds. ;-)
