Rossa di Treviso is a prized Heirloom radicchio from Treviso Italy. It is very cold hardy and will add a striking colour to salads! Leaves start off green and then turn red contrasting beautifully against the thick white stripes and midribs as the weather cools. The tender, slightly bitter leaves are delicious in salads or sauteed with other vegetables. Believed to be good for insomnia and purifying the blood.
