The Story
Plant Bio
Cichorium endivia is a leafy herbaceous annual or biennial that forms a dense basal rosette of edible foliage before sending up erect, branching flowering stems. In summer, the mature stems produce clusters of violet-blue to pale blue, daisy-like flower heads consisting entirely of ligulate florets.
This species encompasses both curly-leaved types with finely divided, fringed margins and broad-leaved escarole types with flatter, smooth-edged foliage. The new growth emerges bright green and matures to a deeper medium green, offering a crisp texture and a characteristically bitter flavor profile.

Planting
How to Grow
- Sow seeds directly into organic-rich, well-drained soil in early spring or late summer.
- Thin seedlings or space transplants twelve to fifteen inches apart to ensure adequate air circulation.
- Maintain consistent soil moisture, as water stress triggers premature bolting and intensifies bitterness.
- Harvest the entire rosette at maturity, or gather outer leaves individually for a continuous harvest.
Pro Tip
Blanch the inner leaves two to three weeks before harvesting by tying the outer leaves together over the center on a dry day; this excludes light to reduce bitterness and prevents moisture from trapping rot inside.

Care Guide
Do
- Keep the soil consistently moist to prevent the plant from bolting.
- Ensure the planting site has excellent drainage to avoid root rot.
- Space plants adequately to maintain good air circulation around the foliage.
Don't
- Do not allow the soil to dry out completely during hot weather.
- Avoid overhead watering, which can trap moisture in the dense rosette and encourage fungal rots.
- Do not blanch the leaves when they are wet, as this causes the inner crown to decay.
