Yes but it doesn't stop my most shaded north facing border from growing with gay abandon. Mine is also damp so I grow hostas, astilbes, ligularia, primulas, ferns, chelone, lily of the valley, astilboides, Japansese anemone, hakonechloa and daffs and snowdrops in there.
I have three smaller drier beds with clematis Minuet, Caerulea Elegans, Nelly Moser, Rahvarinne and Blue Angel plus bergenia, hostas, hardy geraniums and alliums and a Falstaff rose.
A bed a bit further from the house which gets sun a bit earlier has clematis, roses, primulas, dicentras, clematis, echinops, hardy geraniums, achillea The Pearl, lychis chalcedonica, more hostas.
Normal scabious doesn't like my garden conditions but the giant one does. Penstemon and catmint would be best in the sunniest part of your garden.
