flower on onions

Question

My problem is that a small tip on the end of the red onion stems appears to be a small flower about to bloom. Is is to be left alone and allow the onion to grow, pull the onion now (NOT READY), cut off the blooming flower or what?

Answer 1

Most people do cut the flower off because it will sap energy away from making the onion bulb. But, if you would like to have seeds to collect and grow, you can leave it on.

If you want to collect the seeds, you do need to let the seed pod dry before collecting the seeds.
