Green Ice
55d to harvest
Cool, crisp leaves unfurl in a pale green that looks like fresh morning light—Green Ice delivers a refreshing crunch with a clean, gently sweet flavor. Loose-leaf heads form quickly, with tender, ruffled texture that stays pleasantly crisp for salads and quick garnishes. Grow it for reliable early harvests and a bright, garden-fresh bite that shines in fresh servings and leafy blends, as well as in chilled, tangy preparations.

Frequently Asked Questions
What pest or disease is most likely with Lactuca sativa (lettuce) and how do I manage it?
In home gardens, lettuce commonly gets downy mildew (often showing pale yellow patches with fuzzy growth on the underside) and aphids that cluster on tender new leaves. Remove affected leaves early and improve airflow; water the soil, not the foliage, to reduce mildew spread. If aphids appear, spray plants with a strong jet of water and repeat every 2–3 days until clusters drop off, avoiding soaking the leaves.
How can I tell when Lactuca sativa ‘Green Ice’ is ready to harvest?
Harvest when heads (or leaf mass, if you grow it as loose leaf) have reached a usable size and leaves are firm, not limp, typically around 55 days from sowing. For the best flavor, pick in the morning when leaves are crisp, and stop harvesting when plants start sending up a flowering stalk (bolting).
