for necture no they are not but for pollan they are as the bees can get to it , the street trees by me which are cherry apple type dont know what and a few others are all starting to bud up so give it till early march and the flowers will be out, if we get a warm spell evan sooner. the thing is it realy depends where you are and whats on the go , being a birmingham based i get a very nuch larger choice than i ever did in wales or south warwickshire, i could see flowers in gardens in late winter this year as every thing was so far out of plan
haw thorn should start as the black thorn finishs which were i am is around early aprill and yes admin at around the apple and pear season, but some thing do get into flower earlier than normal
