From left to right these are Albino, Early Wonder and Golden beets. This picture is taken when raw, and they will lose some of the color when cooked. In particular the distinction of the rings will fade. They all have slightly different tastes, but all distinctly beet like.
Another beet not shown here, but worth mentioning is the Chioggia beet. It has very distinctive peppermint like rings of red and white, and looks great when served raw as a garnish. I didn’t grow it this year, because I am not very fond of the taste.
