Origins

Stupice

A Czech-bred, potato-leaf early tomato that reached American growers in the 1970s seed exchanges. Cold-tolerant and absurdly early for real tomato flavor; a Pacific Northwest staple.

Early Girl

The early-season standard since the 1970s, introduced to America through Burpee. Famous twice over: as the first ripe tomato in millions of gardens, and as the dry-farmed signature crop of Northern California market farms.
