Beta vulgaris subsp. cicla
Leafy green vegetable with large leaves and colored stems, highly nutritious and versatile in cooking. Grows quickly and tolerant to variable conditions.
Swiss chard needs between 5 and 8 hours of direct sunlight per day and should be planted in spring or autumn in fertile, well-drained soil rich in organic matter. Water regularly and moderately, keeping the soil slightly moist but never waterlogged, especially during active growth periods. It is a hardy plant that tolerates light frosts down to -5 °C, making it ideal for Mediterranean climates and mild winters. Harvest the outer leaves from the base once they reach a suitable size to encourage the plant to keep producing new growth.
