Hi Wiktor.....Nice looking little mugo you have there. Im wondering if there is a slip-up on the name your looking for. I did a little searching around and couldnt find anything!
Best of luck!

Hi Wiktor, this is probably a seedling selection that never made it in the trade.
Maybe you can change this...

Looks silvery, like it's P. sylvestris.

Thank you all for help!
I think that salesman forgot the original name and create his own 'Globosa Compacta'. Coniferjoy you can be right but I can't check It anywhere. I am going to give her only a number to catalog.
Thank you so much one more time :)
bboy: it's definitely not Pinus sylvestris, please look on the buds.
Greetings Wiktor
