'Genovese'
Classic Italian large-leaf type. The standard culinary basil; large, cupped, intensely aromatic leaves.
'Devotion'
Rutgers downy mildew-resistant release. Genovese-type flavor and appearance with DMR genetics.
Heat-loving annual that struggles in cool maritime springs but thrives July through September. Raised beds warm faster on clay soils. Downy mildew (Peronospora belbahrii) is a significant threat in this region's humid conditions.
