Lollo Rossa Darkness

Lettuce

45d to harvest

Sink your senses into Lollo Rossa Darkness—an intensely alluring rosette of frilled leaves that reads like burgundy velvet under garden light. Expect a crisp, tender bite with a lively, gently sweet edge, plus a deeper, darker coloration than classic Lollo types for striking salads and garnishes. Grow it for fresh, spoonable leaf salads and for vivid, color-forward bowls where its ruffled texture truly shines.

Frequently Asked Questions

What’s the most common disease problem for Lactuca sativa (leaf lettuce) like Lollo Rossa Darkness, and how do I treat it?

Leaf lettuce is especially prone to downy mildew and botrytis (gray mold) when leaves stay wet and air movement is poor. Water early so foliage dries quickly, space plants so air can circulate, and remove any yellowing or gray-spotted leaves immediately. If disease is spreading, apply an approved fungicide labeled for lettuce downy mildew and rotate to a different mode of action the next round to prevent resistance.

How often should I water Lactuca sativa during the main growing phase?

During the 35–45 day growth window, keep the top 1–2 inches of soil consistently evenly moist—never waterlogged. In typical home gardens, this often means watering lightly 2–4 times per week depending on heat and container vs. bed conditions, and adjusting to prevent drying out between waterings. Mulch lightly around the plants to stabilize moisture, and avoid wetting the leaves to reduce lettuce disease pressure.

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

Harvest about 45 days from sowing when the rosettes are firm and the outer leaves are full size for your spacing. Snip outer leaves first for a longer harvest, or harvest the whole head/rosette when it holds shape and the leaves are crisp rather than limp. If the center starts elongating or getting bitter, harvest promptly to avoid bolting flavor changes.
