Golden barrel cactus for zone 8?

Asked March 10, 2019, 7:21 PM EDT

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

Thank you for your question. The following source indicates they are hardy in USDA zones 9 to 11, and not down to 8: http://florawww.eeb.uconn.edu/198502247.html

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.
