Red Mountain onion seeds

These seeds were great. I had a lot of onions.

The truth about my luck growing onions

The PATTERSON onion seeds and the RED MOUNTAIN onion seeds had great germination and vigorous growth. The Patterson onions have kept well over winter. This is the first year I have planted Red Mountain. It will be fun to see how they produce.

Delicious onion, excellent for storing

I started these onions later in Feb. with excellent germination. Planted outside after the first frost, end of May (?) in a raised bed, watered when needed, they grew nicely. Mild flavor, excellent for pickling. They are keeping very good in my basement. I will plant them again. I live in north central Wisconsin.
