Plum Lemon 
80 days,
indeterminate — We originally began growing out this variety because of its interesting fruit shape. It truly looks like a lemon in both shape and color.
The regular leaf plants produce fruits that weigh one to three ounces, are typically two-celled, and fairly hollow. They have a very mild flavor. Quite a novelty.
This variety was collected in 1991 by Kent Whealy, co-founder of the Seed Savers Exchange, from a elderly seedsman[1,2] at the Bird Market in Moscow. Each packet contains approximately 20 seeds.
