Nonna Agnes’s Blue / San Bernardo Blue Bean Seeds – 15 Fresh Seeds

Nonna Agnes’s Blue, also known as San Bernardo Blue, is an exceptionally rare Italian heirloom climbing bean prized for its extraordinary blue-coloured seeds.

The mature dry beans can develop beautiful shades of slate blue through to an intense sapphire blue, making this one of the most unusual and visually striking bean varieties we grow. The depth of the blue colouring can vary depending on growing and ripening conditions, giving each harvest its own character.

Plants are vigorous climbers and require canes, trellis or another strong support. They produce pods containing the distinctive beans, which can be allowed to fully mature and dry on the plant when growing for dried beans or future seed.

Originally preserved as a rare Italian heirloom, the variety has circulated under the name Nonna Agnes’s Blue and is also known as San Bernardo Blue or Azzurro di San Bernardo.

An excellent choice for collectors, heirloom vegetable enthusiasts and growers looking for something genuinely unusual.

Our Nonna Agnes’s Blue beans have been grown and harvested by Red Dragon Seeds in the UK, with only a very limited quantity available from each harvest.

Growing Nonna Agnes’s Blue / San Bernardo Blue Beans

🌱 Sowing Indoors: Sow from April to May, approximately 3–5 cm deep in individual pots. Keep warm and provide plenty of light once seedlings emerge. 🌤️ Sowing Outdoors: Sow directly from May to June once the risk of frost has passed and the soil has warmed. 🌡️ Germination: Best germination occurs in warm conditions of approximately 18–25°C. Avoid keeping the compost excessively wet while seeds are germinating. 📏 Spacing: Plant approximately 15–25 cm apart, allowing sufficient space for vigorous climbing growth.🪴 Support: This is a climbing/pole bean and requires tall, sturdy canes, netting or a trellis. Provide support early so the young vines can begin climbing naturally. ☀️ Position: Grow in a warm, sunny and sheltered position in fertile, well-drained soil. Beans appreciate moisture during active growth and flowering. 💧 Watering: Water regularly during dry weather, particularly once flowering and pod formation begin. Mulching around the plants can help retain moisture. 🌿 Feeding: Incorporate well-rotted compost or organic matter before planting. Once flowering begins, an occasional high-potash feed can help support pod production. 💙 Harvesting for Dry Beans: For the characteristic blue beans, allow the pods to mature fully and begin drying on the plant. Harvest the pods during dry weather and finish drying the beans thoroughly indoors before storage. ⭐ Colour: The intensity of the famous blue colouring can vary according to growing, ripening and environmental conditions. Cooler conditions during seed maturation may encourage stronger blue coloration. 📦 Storage: Once completely dry, store harvested beans somewhere cool, dark and dry.
