Asparagus officinalisHeirloom variety developed by JB Norton, USDA, 1919.
Large early green stalks tolerate heat well and demonstrate good resistance to rust. For those of you who know your antique asparagus, Mary was selected from Martha. Of the two, Mary is earlier, more vigorous and more uniform.
A parent to many modern varieties and planted in American gardens for more than a century. We’re excited to offer this for the first time ever. Very winter-hardy. Z3/4. (large-rooted 1-yr crowns)
