I think Carpobrotus chilensis (USA), which is distributed in California as per Jepson
please note in Carpobrotus chilensis, which I have uploaded separately (Carpobrotus chilensis from California-GS10022020-2 (google.com), leaves are glaucous, rounded on the back, flowers are hardly 3-5 cm across, is wild on coastal dunes. This one is cultivated, leaves with flat faces, isosceles triangular in cross section, flowers much larger.
Please note C. acinaciformis has also been introduced into California. We may have to shift upload by … also to C. acinaciformis.
Here is the Link Carpobrotus chilensis in Flora of North America @ efloras.org
Carpobrotus chilensis, I hope.
In light of my new upload and discussion therein, this upload by … may also belong to C. acinaciformis.
