I just lost a Harry Lauder Walking Stick to that disease they are susceptible to (forget the name). Anyway, it is toast and on the burn pile. I am looking to replace with something less prone to disease that will also provide winter interest on my back deck. Either evergreen or interesting branching. The deck has southwest exposure, in full sun, with the prevailing wind also coming from the west. I am in Zone 8 of the Pacific NW, fairly mild winters with freezing but usually not very much snow. Warm summers, not too hot. Lots of rain. Any suggestions?
