(F1) Corn Seed
Product ID:

New! First-early (sh2) variety with improved vigor.
Dependable and tasty, Bolt XR comes in early yet has excellent husk protection. Large kernels provide a satisfyingly deep bite and excellent sweetness. Its early vigor may rival that of synergistic varieties which are often the choice for first planting dates.
