Q.Winter protection for Datura
We live on the West Coast of British Columbia. Zone 8 (Canadian system). Do we need to keep our Datura (Trumpet Flower) inside during the winter? It is in a pot now. Occasional winter snow, wind, rain. and temp. may be below 0 degrees Celsius (32 F.) on occasion.
Datura is occasionally hardy down to zone 5.
You should be fine to leave outdoors in your zone, but you always need to keep into account weather trends.
Since it is in a pot you may want to move to a sheltered location to be safe.
