Ready for winter

Australian laurel, Pittosporum, has to be kept away from the frost. (The last picture.)The same goes for figs and eucalyptus. We have a little room on the balcony with a frost gard radiator. My pots outdoors have got their "winter dresses". My cyklamen on the balcony stands a good deal of minus degrees - the question is how many? The barrel by the entrance has already got a little Christmas tree, that has survived there for a couple of years. I add two different scimmias and a few red cornel branches. (I just love them! You can put them everywhere - directly into the ground if you want to!) Some nice stones added of course - very nice material - stands the frost all the time! ............................................
