Pepperoncini Clarification

True pepperoncini (Greek/Italian pickling pepper) is a specific variety—small, wrinkled, mild heat. Marconi types are larger, sweeter, for roasting. Both pickle well. Choose based on your preferred final product.

Growing Tip

Peppers need 8+ hours sun, consistent moisture, low-nitrogen fertilizer (5-10-10) at bloom and first harvest. Stake early—heavy fruit loads break branches.

Any elongated sweet pepper makes great pepperoncini. Pick your favorite catalog and grow several.
