The comparison is not very precise but should be thought of as indicative only. However you need to factor in the photo period due to latitude as well as we are both very slightly short of 58 degrees North. This will, with climatic zone explain the Narcissus behaviour as I would be astonished if mine came into flower before March. Also his lowest temperatures might be on rare occasions down to - 1C to -5C max, while mine is regularly down to - 10C to - 18C with occasional -25C. This June on the 19th we had -4C as well as three others 0C to -2c that month. Global warming? not here it aint. The June temp was facilitated in part by the fact that at that time of year we have no darkness, here you can read a newspaper at any hour day or night if cloud cover is non existent, a factor I suspect in allowing the temp to drop to -4C. I am not too savvy with the PBS system so would have preferred to post this there for others to comment but I foul up more times than not, please feel free to pass it along to them if you fell it might be of interest. Just a dozy Highlander trying to catch up on technology. Best wishes, Iain Iain Brodie of Falsyde Auchgourish Botanic Garden & Arboretum
