Thanks you both for your replies.
Nutcutlet - There are three trees on that side of my garden. I just been out and measrued and the nearest is about 9 feet and that's the nearest tree to the plant in the flower bed. Its a Prunus Cerasifera Nigra (Purple Leafed Plum).
I have also tried to dig one of them out but the roots are woody and deep (Disturbed the allium bulbs as well that what the white objects are in the photos) See the photos below.
The leaves don't match any on my three trees, but I am inclined to think they are suckers.
What is the best way to get rid of them?
