Perpetual Spinach Swiss Chard Seeds

Perpetual Spinach Swiss Chard Seeds


Despite its name, "Perpetual Spinach" is actually a type of Swiss chard. An old, Italian heriloom, this variety is also known as 'Bietola a Costa Fine' which means 'Swiss chard with thin ribs' in Italian. Becuase it is slower to bolt in hot weather, this variety is a perfect choice for warmer climates. Great as both baby greens and full size. Buon appetito!

Growing Info

Harvesting: Pick up to 1/3 of the outer leaves as needed, and let more leaves grow from the center of the plant; or, if desired, harvest the whole plant 2" above ground, and it will grow back. Pick very young leaves, at 2"-4" for using fresh in salads.

Special Care: Swiss chard "seed" is actually a dried fruit with several seeds, therefore, seedlings may emerge closely, making early thinning important. Thin newly emerged seedlings by pinching or cutting them off at the soil surface, to minimize disturbance to neighboring plants. Cultivate very lightly, as roots are close to the surface. Mulch soil surface when plants are 2" high to keep roots cool and moist. If the plant starts to bolt during the summer, cut off the flower stalk. Rotate Swiss chard (and others in the Amaranthaceae Family) location so they are not grown in the same area more than once every 3 years.
