Planting Claytonia (Miner's Lettuce)
Claytonia (Miner's Lettuce) is a cool season vegetable in the Montiaceae family. Getting the timing right is the difference between a strong stand and a disappointing one, so the windows below are given relative to your own last spring frost and first fall frost rather than a generic calendar date. Look up your local frost dates and count back or forward from there.
You can sow Claytonia (Miner's Lettuce) directly into the garden 4–6 weeks before your last frost.
For a fall crop, sow 6–8 weeks before your first fall frost so plants mature as the weather cools.

Conditions and Care
As a cool-season vegetable, Claytonia (Miner's Lettuce) does its best growing in the cooler weather of spring and fall and tends to bolt or turn bitter in summer heat. It is frost hardy and can shrug off light freezes, so it can stay in the ground later into the season than tender crops.
Claytonia (Miner's Lettuce) grows well in partial sun and tolerates some afternoon shade, which can help slow bolting in warm weather. Sow seed about 0.25 inches deep — small seed is sown shallow and barely covered, then keep the soil evenly moist until seedlings establish.
Claytonia (Miner's Lettuce) belongs to the Montiaceae family; rotating where you grow members of this family each year helps limit the build-up of soil-borne pests and disease. Claytonia (Miner's Lettuce) is generally grown as a single planting each season rather than succession sown.
