Suckers are just shoots coming from the root, they are part of the plant here. but can be a nuisance when they appear in the middle of the border. Snow berry can be cut right to the ground and will come back
Troublesome suckers are when the root is different to the top growth (eg roses), the rootstock is a stronger grower than the top. Growth from that rootstock will take over.
