I was rummaging in the seed stash and these are some of the other "small" squash I have grown in past seasons.
Butter Baby
Honey Baby
Thelma Sanders Sweet Potato
Autumn Frost
South Anna
Reno F-1
and the one that got me hooked on growing smaller butternuts was
898 Experimental (now called Honey Patch) from Row 7.
Each year I try new and different butternuts looking for the one that will be wildly successful in this area. Meanwhile, they all produce and convince me that I am partial to the butternuts.
