🍅 Quick take: Grandfather Ashlock is a mid-season, indeterminate heirloom. It’s an old Ashlock family heirloom from Kentucky. The true variety features potato leaf foliage and produces large, highly uniform, oblate pink beefsteaks. Growers praise its outstanding, sweet, and tender flavor. Keep an eye out for regular leaf off-types in seed batches, which tend to produce redder, less authentic fruits. Full summary ↓

This is an heirloom from the Ashlock family, USA. Potato leaf.
I ran two vines of this in the greenhouse. One was regular leaf, the other was potato leaf. The regular leaf one was obviously an off-type. Its tomatoes were way more red than pink.
The potato leaf vine turned out highly productive, growing to about 6.5 feet (2 m), mid-season. Large, oblate pink fruits. Super tasty, sweet, and tender.
