Variety description

10 August 2026

The Bison variety is classified as lamb's lettuce (Corn Salad, Feldsalat). In some patent documents, the name is erroneously linked to the lettuce (Lactuca sativa) crop, but current registries confirm the variety belongs specifically to Valerianella.

Detailed morphological traits, such as rosette height or leaf shape, as well as specific characteristics of disease resistance, are not described in open publications.
