GF a lot of what you call perennials would probably not survive here, the perennials die right down so does the roses even the canes sometimes but they wake their sleepy heads every spring to start a year anew. Succulents there are only a few that survive our winters and they just kind of go dormant. Its amazing how they do survive year after year growing from bulbs or roots that survived in the ground over winter. Some bulbs we let die back and take in, replanting the following year. Better I try to explain it with pictures. Spring, summer and winter at the cottage. All my garden is perennials that survive a winter of snow and -30 degree weather.
