One of the Begonia grandis in my mom’s garden, bloomin some male flowers right now. This plant is hardy to zone 6 and we are borderline 6a, some winters more like 5 which then tend to be followed by really wet springs in clay soil which most plants that like good drainage don’t appreciate… but both clumps have come back two years, albeit slowly. This year I took cuttings and plan to take more before the frost, just in case.
