The veggie garden is ankle- to calf-deep in miner’s lettuce this time of year. It began with a single generous packet of seed a few years ago, and now it comes back reliably–if by “reliably” you mean “with a vengeance.”
Calflora shows Claytonia perfoliata to inhabit many coastal valley to foothill locations statewide. And there’s a herbarium sample that was collected just down the block from me. It can get by with no added water, but will give you a nice kitchen crop when kept just-moist. Sun exposure: full sun to dappled shade. It’s pretty adaptable and just about the easiest thing to grow.
Edit, March 15, 2023: In the 5 years since I wrote this appreciation the colonial name of “miner’s lettuce” is being retired for the less colonial name of “indian lettuce,” or, probably better, “rooreh,” its name in the language of the Ohlone people, one of the peoples to have used (and to currently use) this plant. “Rooreh” is now the common name you’ll find listed in many sites, including the Jepson e-flora.
I’m very fond of plants with perfoliate leaves. This looks like a great native for California gardens.
That is the sort of vegetable growing that appeals to me.
