You may have difficulty getting any flowers to bloom even with hanging baskets. Perhaps you could add some standing metal trough planters , fill with greens and maybe some shade flowering plants. If you place them under your windows, they will be seen from the street. LOVELY home. Some examples:

I would put a couple of nice chairs with a small table in a bright color a great place to enjoy a glass of wine on a hot day. I live the fushia pink in your flowers. and while you are at it get rid of the shutters and paint your front door.

I agree with the suggestions above. I would not do the hanging baskets only because they would close in and make your porch even darker underneath, perhaps also blocking more light to your windows. A large, colorful glazed ceramic pot with some Impatients (they do very well in my north-facing always-shaded planting area) perhaps flanking the door would be a good start. Add a few white or colorful chairs with a small side table and you've got something light and bright to draw the eye in. You have a beautiful home.

Hello Nan K, I have an alternative suggestion to the flowers that be a more colorful impact. Would you consider Outdoor panel drapes, they add touch of color with the architecture of the home. A colorful stripe of summer colors would be a nice year round addition to the porch and stone facade. The photos show more subtle tones but your home should have colors you like.
