History and provenance
This is a perennial food crop whose first-year growth does not equal a mature harvest. Seed-grown plants establish genetic diversity and may take more than one season to reach full production, so establishment timing and mature harvest timing are kept separate. Romanesco is used for more than one regional artichoke selection. The exact identity or lineage of this seed lot should be confirmed from supplier records before making a stronger claim.
