Lollo Rossa

Lettuce

45d to harvest

Lollo Rossa unfurls into a velvet rosette of wine-red frills, the leaves crisp and tender with a gentle, sweet bite and a pleasantly mild edge. Expect a loose, airy texture that stays beautifully fresh through the season, making it a standout for gardeners who love color as much as flavor. Grow this heirloom for bold, spoonable greens—ideal for fresh salads and vibrant garnishes, and equally lovely when tossed into quick sauces for a rosy, leafy finish.

Frequently Asked Questions

How often should I water Lollo Rossa during its main growth (about weeks 2–6)?

For Lactuca sativa, keep the top 1 inch of soil consistently moist during the main growth phase—typically watering every 1–3 days depending on heat and wind. If leaves start to look limp or edges brown, increase frequency, but avoid waterlogging because soggy soil can worsen root and crown issues. Aim for deep, slow watering that wets the root zone instead of frequent splashes.

How can I tell when Lollo Rossa is ready to harvest?

Harvest when heads are firm and leaves are fully expanded, usually around 45 days from sowing, and before the center starts to stretch upward. You’ll know it’s time when the frilly leaves hold their shape and the plant isn’t getting noticeably taller or loose—lettuce that tips too far toward bolting will turn bitter quickly.
