Welcome, welcome Greta Greta
as many may know here I am very fond of Taxus Standishii. A very colourful, classy, bombproof erect yew. This will grow there.
will some sun you could check out Aster Frikartii too. Lavendar blue flowers from mid summer through to autumn. hardy geraniums like Orion, Elke, Rozanne too. clematis like Nelly Moser will look good on the fence. Phormiums like Sundown will provide evergreen colourful foliage. dahlias will add quick summer colour. Verbena Bonariensis will,give you colour up to 7' on strong thin stems all summer....a real fwvourite.
If your soil has reasonable moisture you can plant astrantias and heleniums as well as astilbes and tall grasses like calamagrostis Karl Foerster which will flower wll summer.
lots of things you can plant to quickly transform that spot Greta
