Elevate your garden with Marconi Sweet Pepper Seeds, an Italian heirloom variety known for its exceptional sweetness, robust growth, and versatile culinary uses. These Capsicum annuum seeds produce peppers that are slightly larger and sweeter than traditional bell peppers. Each fruit can reach up to 7 inches long and offers a mild, sweet flavor that enhances a variety of dishes, from fresh salads to roasted meals.


Why Choose Marconi Sweet Pepper Seeds?

1. Heirloom Quality for Superior Flavor

As an Italian heirloom variety, these peppers have been passed down through generations, retaining their original, sweet flavor and vibrant color. Unlike hybrid varieties, heirloom seeds produce plants with consistent traits, ensuring that every harvest is as flavorful as the last.

2. Non-GMO & Open-Pollinated for Natural Growth

Our non-GMO pepper seeds are open-pollinated, meaning they are naturally pollinated by insects, birds, or the wind. This results in genetic diversity and allows you to save seeds from your harvest for future planting, preserving this heirloom pepper variety for years to come.

3. Versatile Culinary Uses

These Italian sweet pepper seeds grow into peppers with a versatile flavor profile, making them ideal for a wide range of dishes. Whether you prefer them grilled, roasted, sautéed, or eaten fresh, these peppers deliver rich, sweet flavor that enhances any meal. They are perfect for stuffed peppers, sauces, stir-fries, or as a colorful addition to salads.

4. Eco-Friendly Packaging & High Germination Rates

We care about both your garden and the environment. Our seeds are professionally packed in eco-friendly, resealable packets made from recycled materials and printed with vegetable-based ink. Additionally, we regularly test our seeds to ensure high germination rates, giving you the best chance of a successful, abundant harvest.


Planting & Growing Instructions

When to Plant:

Start seeds indoors 6-8 weeks before the last expected frost date in your area. Once seedlings have grown strong and the outdoor temperature remains consistently above 60°F (15°C), you can transplant them outdoors.

How to Plant:

  1. Start Indoors: Plant seeds ¼ inch deep in seed-starting mix. Keep the soil moist but not waterlogged. Place them in a warm, sunny spot or under grow lights.
  2. Transplant Outdoors: Once seedlings are about 4-6 inches tall and the danger of frost has passed, transplant them to your garden or containers. Space plants 18-24 inches apart.
  3. Watering & Feeding: Water regularly, keeping the soil evenly moist. Use an organic fertilizer or compost to promote healthy growth.
  4. Harvesting: You can harvest peppers when they are green for a mild flavor or let them ripen fully to a deep red for maximum sweetness.
