Golden barrel cactus for zone 8?
I have a a golden barrel cactus living indoors that I would like to acclimate to living life outdoors. I have heard from different sources that these cacti can live in USDA zones 8-11, and I live in zone 8 (Portland metro area). I already have some opuntia, cholla, sempervivum, and sedum living outdoors doing just fine, but I wanted to get an expert opinion before I made a decision. So can golden barrel cacti live outdoors in my area?
Multnomah County Oregon
There are no areas of Multnomah County that are in zone 8. (You can find your exact zone by using this zip code method: https://planthardiness.ars.usda.gov/PHZMWeb/
Zone 9a would be a low temperature spread of 20 to 25 degrees; zone 8a would be a low temperature spread of 10 to 15. These succulents will freeze at the temperatures we have been having, so I would advise that you keep it as an indoor plant except during the summer months. Hope this is helpful. Good luck!
I believe Kris meant to say there are no areas in Multnomah County that are Zone 9, not Zone 8. Most of Multnomah County are Zone 8b.
