Rossa di Treviso, organic seeds

Eco Heirloom variety

Information

Is a pretty, elegant lettuce from Treviso in Northern Italy. The head is torpedo-shaped and becomes a deep wine-red when the weather grows cooler in autumn. The leaves resemble small boats of intense contrast between the shining wine-red of the leaves and the dazzling white nerves. Rossa di Trevo, which was already grown in the 1700s, is tender with a faint bitterness. Roots can be stored and forced as winter lettuce. A portion contains about 300 seeds.

Cultivation advice

Sowing

Sow 1 cm deep, when the soil has warmed up to at least 10°C. The risk of bolters from the plant grows when the soil is too cold.  

Spacing

Thin out to 20-30 cm between the plants and 40-50 cm between the rows.

Harvest

Lettuce-chicory is cultivated because of the leaves and heads and can be harvested far into autumn. The root- or forced chicory yields a strong pole-root for forcing during winter. It can be dried, toasted and ground for coffee surrogate, which is very common on the continent.
Roots for forcing are harvested late. Cut off the tops a few cm above the neck of the root, trim and shorten to 15-20 cm. Let them dry a little before storing in the same way as carrots. To force-grow pack them close together in a deep box or bucket with soil, moist sawdust or peat. If the space they are in is absolutely dark there is no need to cover, but the best crop comes from covering the roots with a 20 cm thick layer of dry sawdust or peat. Keep the box in darkness at a temperature of 15-20°C. After 4-6 weeks yellow-white, crisp heads can be harvested. If lighted they turn green and bitter.
