Snow is not so rare in southern Norway in April. Luckily, I'm in northern Greece now, waking up to 7 degrees this morning and very strong wind was not so wonderful either. There was a cold spell around Christmas here (down to minus 5 degrees C) killing most of my potted plants, some of them I have had for around 20 years. Everybody around here have lost a lot of plants as well. Fortunately, most of those in the ground seem to have survived.
