Another Chilean native that has become a go-to plant in our drought tolerant California landscapes: rock purslane (Calandrinia spp.). The species from Chile most commonly in our gardens is C. grandiflora.
These are wonderful plants: sun-loving succulents that produce extravagant displays of intensely colored flowers but require little water -- even to withstanding complete soil drying -- and are DEER RESISTANT. They do best with good drainage but can tolerate some clay. They are considered half hardy, so plant them where they will get protection from the worst of our Bay Area cold.
BTW, does it remind you of a California wildflower? It should: it is related to our spring annual, the equally brilliantly colored annual red maids (Calandrinia menziesii).
