In a pot or in the ground?

Where are you, other than in a 9b zone? Micro-climates can be quite helpful, especially with an alert gardener willing to add protection if temps plunge..

It’s in the ground , and it’s zone 9b Northern California. I think frosts can occurs sometime in December to maybe February. I’m not certain but I think frost occurs usually in late December or in early January

in the ground that might kill the plant. I know you can leave it out in 10a - my zone, have done so many years. but heres what happens. the plant loses nearly all its leaves. it goes into a dormant state to wait for warmer weather. any sustained time under freezing and you may not have a plant in the spring. now - things that matter - size of the plant. is it covered and mulched up during the frost times? if the plant is young then I would say dig it up and move it to a protected spot for the winter. if its a few years old , has a nice thick base and of say over 4 ft tall, then it may survive. but i would still be looking to keep the core warm during the worst of the cold. things like a garbage can over top with some water pans inside - if the water is warmed during the day it can help keep the plant warm in a closed space overnight... I had 2 plants in pittsburg that I didn't do anything with over winter - they survived but were definitely stunted in growth.
