View photos of the edible plant, Claytonia perfoliata (Miner’s lettuce), profiled in the Wild Edible Series: California: Vol 1, Nevada, Oregon, Sonoran, Utah, and Washington.

A passage from Wild Edible Plants of California: Vol 1:

All members of the Claytonia genus are edible. For compartmentalization purposes, I’ve listed the annual California plants with wide leaves as ‘Miner’s lettuce’, except for Claytonia sibirica (Candy flower), which is a wide–leaved perennial (with edible roots).

A passage from Sonoran Desert Food Plants:

Like Purslane, Flameflower, and Jewels of opar (same family), all parts of Miner’s lettuce are edible. Mildly tart
and succulent, it is one of the most refreshing wild edibles we have in Arizona.

A passage from Wild Edible Plants of Utah:

Miner’s lettuce is a common western US annual. In Utah, it mainly grows in and around the central ranges, then west. Surprising variable in elevation requirement, it’s usually found between 4500’–8000’.
