Hendersonville falls in both the short-day and intermediate-day range.
I found a site for Dixondale Farms (located in Texas); they recommend these short-day varieties:
1015Y Texas Super Sweet
Red Creole
Southern Belle Red
Texas Early White
Texas Legend
White Bermuda
Yellow Granex
They also sell a short -day sampler so you can see which varieties do best for you.
Looking in our ATP Green Pages there are 3 very positive reviews (one is from
@dave) for this company; guess they know their onions!
