Seed Saving

Chard

Chard and beetroot are the same species grown for different parts of the plant -- one for its leaves, one for its root -- which means if you grow both and let them flower in the same season, you'll get an unpredictable cross rather than true seed from either.

How It's Pollinated

Wind-pollinated (high outcrossing)

(High crossing risk)

Scientific name: Beta vulgaris

Domestic Crops It Can Cross With

  • Other chard varieties
  • Beet / beetroot -- same species (Beta vulgaris) and will cross freely if both are allowed to flower nearby

Wild Relatives & Feral Species

  • Wild sea beet grows on some coastlines and can cross if present nearby

Separation Distances Required

Minimum: 500m between varieties

Recommended: 800m-1km for reliable purity

Strict: Bag and hand-pollinate flower spikes for guaranteed purity

Seed-Saving Strategies

  • Biennial -- overwinter roots (mild zones) or lift and store, replant in spring
  • Allow seed spikes to dry brown on the plant
  • Strip seed clusters by hand once fully dry
  • Store dry -- viable 4-5 years
