Swiss Chard
Beta vulgaris subsp. cicla
Swiss chard is the same species as beet — selectively bred for leaves instead of roots. A single seed of 'Five Color Silverbeet' produces multi-colored stems within the same plant because the variety is a population, not a single genotype.
How to care for swiss chard
Cut-and-come-again — harvest outer stems repeatedly for 6+ months while the central crown keeps producing. Heat-tolerant unlike most leafy greens — produces all summer where lettuce bolts in June. 'Bright Lights' cultivar yields rainbow stems.
