HERB ‘Cress – Upland’ Seeds
Botanical Name: Barbarea verna
Upland Cress, also known as American Cress or Early Winter Cress, is a hardy, fast-growing leafy herb with a spicy, watercress-like flavour. Unlike traditional watercress, Upland Cress thrives in soil-based gardens and is well-suited to cooler conditions. Its dark green, glossy leaves are packed with nutrients and add a delicious bite to salads, sandwiches, and soups. This resilient herb is an excellent choice for home gardeners looking for a robust and easy-to-grow green throughout the cooler months.
