This was our first year for onions and this was our only onion bloom it is a 10/15 onion.
Not all onions bloom and the bloom is where the seeds are at. If you get no blooms you either buy more seeds or onion sets for the next planting.
These blooms are similar looking to garlic blooms just different color flowers. These two pics were taken 2 different days so you can see the progress of the changing flowers.
All gardens have beauty even before the harvest.
