On Saving a Strain
In the autumn of 1983 the freeze came a week early and took the tomato row in one night. Everything, black. Except the cold frame, where three fruits hung on one Frost Pear vine, amber and smug.
What a strain costs
Rebuilding from three fruits means three families of seed, which means three chances to lock the strain into weakness. We grew them out one fruit per bed for nine seasons, crossing carefully and roguing ruthlessly. Ruth Vernal called those years "the probation." The strain came off probation in 1992 and entered the register with its old name and a new footnote.
What we changed our minds about
For years the register said the Frost Pear was an 1890s strain. The probation taught us the honest version: a strain is not a date, it is a continuity of people. The date matters less than the unbroken line of somebody choosing which fruit to keep. We rewrote the entry. Nobody minded. That is when we started printing grower names on every packet.
“Heirloom is not an age. It is a promise somebody kept.”
The footnote now reads: Rebuilt 1984–1992 from three cold-frame survivors; grown by the Vernal family and fourteen borrowing households. Fourteen names, in pencil, in the ledger. Some of those households still borrow.
