Radicchio – Grumolo Rosso


Packet (~400 seeds)


We were turned onto this Verona-type radicchio by Adaptive Seeds who praised it for its unmatched beauty and cold hardiness. Indeed, it is stunning to witness these deep burgundy rosettes developing through the heart of winter, getting more vivid and filled-out with each passing week.  Leaves are slightly bitter, getting less so with each frost. They are perfect eaten alone in salads or mixed with other hardy chicories, spinach, and kales.  Sow May through September for harvest October through March.

Days to Maturity: 80
Latin name: Chicorium intybus

Planting Instructions:
Plant late spring through summer for harvest late fall through winter. Optimal soil
temp for germination is 70-85°. Planting depth:
1/8”. For full heads – start indoors 4 weeks before
desired transplant then plant at 12-18” spacing
or direct seed every inch and thin to same spacing.
