I never tried to grow swiss chard either. I am going to have to get some to try. I know my Grama has cooked it and I have eaten it but I couldn’t tell you what it was. LOL... I like cooked greens so I just ate what she put in front of me and didn’t always know the difference.
But, I have added that to a list of seeds to pick up next time I’m in town. Just wonder if it’s too late to set them out here.
Chard is a warm weather plant, but if protected, it will grow for a couple seasons.
It is not too late to plant it I would think.
I would say the taste is medium to mild, not like turnip greens and it is good for you.
