Did you know?
Swiss chard is not actually from Switzerland — it was identified and described by a Swiss botanist named Koch in the 19th century which led to the Swiss designation. It is actually Mediterranean in origin and has been cultivated since ancient times. The stems can be red yellow orange white or striped — these are different varieties of the same plant not different species.
