ID a Plant
I am a plumeria grower and a friend sent me some unknown cuttings last season that have grown very well in my rock garden at home. I have attempted to id this plant with a few friends at different botanical gardens with no luck. They suggested asking a few professional growers in Cal. if it could be id by those with more local knowledge. Any help would be appreciated, I have given several cuttings to friends in my area now so many of us are at a loss! I have attached a picture. My friend has told me in late spring in Cal it forms a stalk with a bloom head of multiple purple flowers. Any help would be greatly appreciated so I can give this plant a name.
It looks like you have a very happy Calandrinia grandiflora. It should send up amazing purple, poppy like blooms all summer long. I find they bloom best if ignored and under watered. They are native to Chile and Peru. Though they must come from lowlands, since they do get knocked back with a heavy frost here in Berkeley. I think they could handle more cold if they were drier, but our winters are usually wet.
