Little Gem Darky

Lettuce

55d to harvest

Sweet, crisp hearts emerge in compact rosettes—Little Gem Darky brings a velvety, deep-green beauty with a tender crunch that feels almost luminous. Leaves are richly colored and finely textured, forming a mini romaine head that stays pleasantly snappy as it matures in cool weather. Ideal for fresh salads and garnishes, it also shines in quick tosses and bright, leaf-forward bowls where its compact stature and clean flavor are the star.

Frequently Asked Questions

Why are my Lactuca sativa (Little Gem) leaves developing sticky patches and dark mold, and what should I do?

Sticky residue with black sooty mold on Little Gem lettuce is often caused by aphids. Check the undersides of leaves and hose aphids off with a strong water jet, then release/plant beneficials if available or spray with insecticidal soap in the evening (follow label rates). Remove heavily infested outer leaves to break the cycle and improve airflow so mold doesn’t keep spreading.

How often should I water Lactuca sativa (Little Gem) during the main growing phase?

Keep lettuce evenly moist from transplanting through heading, aiming for consistently damp (not waterlogged) soil. In typical home gardens, that often means watering 1–2 times per week, but increase to 2–4 times per week during hot weather to prevent leaf tip burn and bolting. Use short, thorough watering so moisture reaches the root zone, and avoid letting the soil dry out completely between waterings.

How can I tell when my Lactuca sativa (Little Gem) is ready to harvest?

Little Gem lettuce is usually ready about 55 days after sowing and should feel firm, compact, and “tight-headed” when you gently squeeze it. Harvest when the head is fully formed but before it starts to stretch upward or flower, which signals bolting and a bitter taste. Cut the head at the base in the morning for the crispest leaves.
