Cascaduro Italian Heirloom Sweet Pepper Seeds

Cascaduro — The Italian Heirloom Sweet Pepper With Exceptionally Thick, Juicy Walls

Cascaduro is a classic Italian heirloom sweet pepper prized for its remarkably thick, crisp walls and rich, sweet flavor with absolutely no heat. These large, elongated peppers ripen from green to a deep, glossy red and are equally outstanding eaten fresh off the plant, sliced into salads, or roasted until their natural sugars caramelize into something extraordinary. If you’ve ever had a truly great roasted red pepper — the kind that’s silky, sweet, and deeply flavorful — Cascaduro is the variety that makes it happen in your own garden.

Vigorous, productive plants deliver generous yields of beautiful peppers throughout the season. Open-pollinated and non-GMO, Cascaduro is a variety worth saving seed from year after year.

Growing Notes

Start indoors 8–10 weeks before last frost. Peppers need warm soil (70–85°F) to germinate — use a heat mat for best results. Transplant outdoors after last frost when nighttime temps stay above 55°F. Space plants 18–24 inches apart in rows 24–36 inches apart. Full sun and consistent moisture are essential. Harvest green for a crisper, slightly more bitter flavor, or allow to ripen fully red for maximum sweetness.
