As far as hardiness zones go we would be the equivalent of an American zone 10b. It has never been close to freezing since we moved here in 2016. I can leave my plants outside all winter. They don’t die but they do stop producing pods. The mountains behind us also create a microclimate that keeps the area about 10 degrees warmer than the interior of the country in winter and 10 degrees cooler in summer, so it also rarely gets into the high 90’s but it does stay close to 90 most of the summer with practically no rain between mid May and mid September. We actually chose the area because of the potential views. The weather was just a bonus.
