When I retired I gave real thought to every season and, although I live in a warmer zone, I thought you could look up the hardiness of plants that come to mind, some of which I have here.
Witchhazels, Hamamelis hybrids, yellow and red twigged dogwoods,Cornus sericea and Cornus alba varieties, Holly, both Ilex opaca, red or yellow berried, and Ilex verticillata. Callicarpa. Crabapples and hawthorne, which I do not grow. Some roses with scarlet hips. Acer palmatum 'Sango Kaku'. White, yellow and deep red brown barked birches.The brilliantly barked Salix brixensis. Gaultheria procumbens. Cornus canadensis. Vaccinium angustifolia 'Ruby Carpet'. I suspect some of these are not for your zone, but one or two will not grow well for me in my warmer area.

For winter interest, I find the paperbark maple ( Acer griseum) hard to beat. Another good plant here is the evergreen perennial Bergenia cordifolia ... the large leathery leaves persist and have a bronze coloring during the winter.

Your cold climate will definitely have a limiting effect. Color from conifers and twig dogwoods, willows etc. may in fact have to be the core of it.

Hello, I have found from google top ten winter plants for your reference and I have attached the link below.
