Food crops grown for a season in the listed zones. This does not mean winter frost survival; use local weather and crop timing.

Principal seasonal role

Spring, Autumn

Fit it to the site

Moist, fertile, draining soil. Crop type, season and temperature affect growth and bolting.

Reject a plan dependent on unrestricted summer lettuce where local heat makes it unsuitable. The stated size is a leafy crop, not a bolted flowering stalk.

Keep the care in the decision

Inspect water and pests frequently. Harvest outer leaves or a whole plant according to the selected type. Heat and long days can trigger bolting; a frost calculation alone cannot guarantee a suitable season.

Origin & safety checks

Domesticated crop with origins from the Mediterranean towards Siberia; not a native-habitat recommendation.

Use identified garden seed or transplants, suitable soil and water, and food-hygiene guidance. This is not advice to forage for wild lettuce.

Check current invasive restrictions with your local plant-health or extension authority. For pets, use the exact botanical name in a veterinary toxicity reference; for potential ingestion or exposure, get appropriate professional advice rather than relying on a design guide.
