Red Onion 'Red Brunswick'

'Red Brunswick' is a reliable and popular red onion variety that performs excellently in the UK. This mid-to-late season maincrop onion produces attractive, slightly flattened, globe-shaped bulbs with a deep, dark red skin. Inside, the rings are edged with a beautiful rosy-purple tint, making it a visually striking choice for salads and sandwiches when used raw. Its flavour is relatively mild and sweet, though it develops a deeper richness when cooked. 'Red Brunswick' is noted for its good storage potential, often keeping well for several months after harvest if cured correctly in a sunny spot. It can be grown from seed in late winter or sets in early spring. It prefers an open, sunny site with fertile, well-drained soil and benefits from a weed-free environment. Red onions like this are a great addition to any allotment, providing a colourful alternative to the standard yellow storage onions and offering high levels of healthy antioxidants.
