Red Treviso Radicchio
Botanical Name: Cichorium intybus (Treviso-type radicchio)
Treviso is a classic Italian radicchio, a type of chicory (Cichorium intybus), that forms upright, elongated heads of deep red leaves with bright white ribs. The leaves have a pleasant bitter bite that mellows with cool weather and cooking. Use them fresh in salads, or grill, roast, and braise them.
- Type: Cool-season crop grown as an annual
- When to sow: Early spring, or mid/late summer for a fall crop. In warm regions (zones 8–10), sow August–September.
- Seed depth: 1/4 inch
- Spacing: 8–12 inches apart
- Germination: 3–7 days

Radicchio 'Red Treviso' FAQ
When should I plant Treviso radicchio?
Cold regions (zones 3–6): sow in early spring or midsummer for a fall crop. Warm regions (zones 8–10): sow late summer to early fall for fall and winter harvest, or late winter for spring. Heat causes bitterness and bolting.
How long until harvest?
Most radicchio are ready in about 60–90 days from sowing, depending on variety and season.
Can I grow it in a container?
Yes. Use a pot at least 8 inches deep and keep the soil evenly moist.
Why are my leaves green instead of red?
Red color develops best in cool weather. Fall-grown plants color up much more than spring or summer plantings.
