I have two large pot grown bay trees (Laurus nobilis) which are moved into my porch for the winter. In the summer, they are outside quite near to my oldest Hablitzia. A couple of seeds found their way into the pot a couple of years ago and the resultant plants seem quite happy there, clearly not bothered by not experiencing sub-zero tempreatures (it’s mostly between +5C and +10C) where it’s growing with little light. Last summer it climbed into the Bay in the spring, but died back earlier than my other plants presumably due to the drier conditions in competition with the Bay! Time for a snack soon!!
