Overwintering muir's rhinephyllum — FAQ
Does muir's rhinephyllum need to come indoors for winter?
Muir's Rhinephyllum is hardy to roughly USDA zone 10 — winter lows around -1°C. That means it will not survive frost and needs to come inside.

Move it indoors well before the first frost, give it the brightest spot you have (light levels indoors drop sharply in winter), and keep it away from both cold window glass and hot radiators — the swing between the two does more damage than the cold itself.
