Gardeners' Notes:

I also planted a yellow onion from the grocery store which had begun to sprout. The result was large and gorgeous, white pom pom flowers on tall stalks. They lasted in my garden for a month...! I'm going to plant some other household veggies like garlic and ginger in that area for hopefully, a great look.

I buried a vidiala from the grocery in the ground last year (it was starting to look a bit bad)...anyway, it's been growing/spreading ever since and has stayed evergreen as well. I haven't dug up the area to see what's going on in the ground. However, I will be this season; as I'm changing the bed around that it's in.

Edit: oops, probably should've posted this under the 'sweet vidalia' plant file.

(Also known as Yellow Granex)

A Valadia type onion available from Bonnies Plants.

According to FarmerDill,

"There are almost 30 cultivars registered for the Vidalia Growers Association. Unless grown by association members they cannot be sold as Vidalia onions. All the approved cultivars look alike in the market place, but grower difference are maturity, disease resistance, yield and storability. All are a type of hybrid Granex."

A yellow short day hybrid from Golden Valley Seed. One of the many cultivars grown as Vidalia onions. A short day type that does well here.
