Radicchio Lettuce

Radicchio Starter Plants in 4-Inch or 6-Inch Pots Available in Jupiter, FL

Radicchio (Cichorium intybus var. foliosum) is the jewel-toned heirloom green that brings bold color, crisp texture, and pleasantly bitter flavor to cool-season salads. With deep burgundy leaves and white midribs, radicchio forms compact heads resembling small cabbages, adding a touch of culinary sophistication to any edible landscape. Whether roasted, grilled, or sliced fresh, radicchio shines in winter kitchens—and grows beautifully in South Florida's fall-to-spring climate.

Available in 4-inch and 6-inch pots, these starter plants are primed for quick transplanting into raised beds or containers for easy harvests through the cooler months.

Care & Growing Info (Optimized for South Florida):

Sunlight: Full sun to partial shade. Cooler temps allow it to thrive even in full South Florida sun.

Watering: Moderate. Keep soil consistently moist, especially during head formation. Avoid letting it dry out or become waterlogged.

Soil: Rich, well-drained soil with organic matter. Compost and worm castings help build structure and retain moisture.

Fertilizer: Apply a balanced organic fertilizer at planting and every 3–4 weeks. For tighter heads and deep color, supplement with potassium.

Growth Habit: Compact rosette forming a round head, usually 6–8 inches across. Outer leaves may spread slightly before tightening into the core.

Temperature: USDA Zones 9–11. Prefers daytime temperatures between 45–70°F. Ideal for fall and winter planting in South Florida.

Maintenance: Low. Remove yellowing outer leaves as needed. Watch for slugs and caterpillars—use iron phosphate or BT if necessary.

Harvest & Seasonality:

Planting Time: Best planted from October through February in South Florida.

Harvest Time: 60–80 days from transplant, depending on variety and weather.

How to Harvest: Cut at the base once the head is firm and well-colored. Younger leaves can also be harvested for baby greens.

Seasonal Notes: Cold weather improves color and flavor. Radicchio can handle light frost but not intense heat—bolt risk increases in spring.
