No it's not. Very strange this year, some plants have died due to frost
damage like my Dahlias others seem totally untouched like my Arum Lilies
which are usually the first to turn to mush, saw a dahlia in full flower
yesterday in someone's front garden.


Bob, all my dahlia are black but as I have planted them deeply, they
remain in situ for the winter without any problem.
