Hi, Perhaps it depends on how much winter rainfall these plants get as they came back for me for years when I lived in an area where the amount of rainfall was much less than it is where I now live. They did not come back when I planted them out in my garden here. I looked up and found that the average rainfall where I used to live was 13.84 in (351.5 mm). During the time I planted it here our 15 year average was 65 in (1651 mm). The others in California who have reported that these plants did well with winter rainfall get amounts similar to my former garden. But it also is cooler here in summer and perhaps they didn't get as much moisture as they might have wanted in summer as I watered more in my old garden so other factors could be at play.
