don't know if its a leylandii but I get lots of them and I always pull them up. there is a leylandii hedge across the road and the seeds are very light and are easily carried on the wind.

Not according to the image lower down in this link https://parksandgardensuk.wordpress.com/2015/01/17/almost-everyones-least-favourite-tree/

but I'm not convinced - the only other conifer it could be is Chamaecyparis, which also has flattened sprays of leaves, with four tiny leaves clasped round the stem, very similar to Leylandii

I'm not aware of any Leylandii around here,Sbg..I didn't know the seeds were so light...it probably is then ! :o( I wouldn't mind,but I've sort of nurtured it the past two years,as I couldn't tell what it was till this year ! Lol

Thanks for the interesting link,Bamboo...I'll check out Chamaecyparis.It might still be too big to have in my small garden...

By its growth habit, it's not going to be a dwarf....

No,I didn't think so..It will be gone tomorrow !...

Hi Sandra! I think your first suspicions are correct. I'm almost 100% sure it's Leylandii. I had one that was taken out by my neighbor's fire. Not my favorite tree and I was happy to see it go to be honest. It hogs up a great deal amount of space and it's weak branches snap easily in high winds and any amount of snow & ice - never to recover.

Thanks for confirming what I thought,Paul..It's already been pulled up and disposed of ,as from yesterday :o)
