'Bright Lights' swiss chard was chosen as an All-America Selection Winner in 1998 and is also the recipient of the Royal Horticultural Society's Award of Garden Merit. Grown as an “edible ornamental”, you can see why it is an attractive plant for food gardens. The colours are due to plant pigments called betalains. Betalains are found only in plants belonging to the order Caryophyllales (an order is a taxonomic unit that contains a number of related families), and curiously, the fungal genus Amanita, according to Stephen Nottingham's “Beetroot”.

With a cultivated history extending at least five millenia, quinoa was long a staple food in South America, second only in importance to maize. Displaced in recent modern times by less labour-intensive grain crops, such as wheat or barley, quinoa is experiencing a small resurgence due to its high nutritional value and oils.
