Welsh Onion
Approx. 50 seeds
A reliable perennial onion grown for its mild, hollow green stems and small white bulbs. Welsh Onion is one of the easiest edible crops to grow, returning year after year and providing a steady harvest of fresh onion flavour from spring through to autumn. The leaves can be used much like spring onions or chives, while the entire plant is edible and useful in salads, stir-fries and cooked dishes.
Unlike bulbing onions, Welsh Onion forms clumps that gradually increase in size over time, making it a productive and low-maintenance addition to vegetable gardens, kitchen gardens and edible borders. In summer, attractive globe-shaped white flowers are produced, drawing bees and other pollinators into the garden.
Thriving in full sun or partial shade, Welsh Onion prefers fertile, moisture-retentive but well-drained soil. Once established, it is hardy, dependable and can be divided to create new plants.
