Swiss Chard 'Bright Lights' is a striking looking plant with stems that vary in colour from red, pink, white, violet and golden yellow.
It looks fantastic in the garden or containers and on your dinner plate. I saw it at RHS Wisley where they had planted up a raised brick wall around their coffee shop with rainbow chard. It looked stunning and very appropriate.
It is a close relation to the beetroot family but is grown for its leaves rather than beetroot which is grown for its edible roots. The colourful leaves & stems can be picked whilst young and used raw in salads or left to grow on and used in stir-fries or sautéed in butter (and it keeps it's colour when cooked!).
