If it runs east to west, that seems to mean that it faces north, with the garage behind it, so very little sun. There are lots of wonderful shade plants. Kisal is right, you will need to keep them pretty small and low to be able to get to things. Here's some thoughts:
*bugle weed (aka carpet bugle) is a very low ground cover, it has small not very showy flower spikes in late spring, but comes in a variety of gorgeous rich foliage colors, chocolate, bronze, bluish etc. ( In shade you want to think about foliage more than flowers for your color. )
*Wild ginger is also a low ground cover, a lot plainer, but it's a native and spreads very nicely without being invasive, gives a rich look.
*Other ground covers include lamium, pulmonaria, caladium all with lots of variegated foliage. The lamium and pulmonaria are mostly white variegations, but white shows up very nicely in shade. Pulmonaria is native. The caladium comes in all kinds of fancy colors, reds, pinks, whites, but it is tender and has to be dug up every fall.
*The classic shade plants are hostas, which come in blue-greens, yellow greens, and lots of variegations and a wide variety of sizes and are often fragrant.
*If you can keep it moist enough you could put ferns in with the hostas. Lady fern is a very pretty native.
*Heuchera is another plant usually grown for foliage colors, bronze, purple, gold, striped. Some of them also have pretty showy flowers.Tiarella is a similar but smaller native plant bred for gorgeous foliage, but also in spring has pretty pink flower spikes (they've actually been hybridized into heucherella.)
*For flowers there's bleeding heart, epimedium, columbine.
* One of my favorite shade plants, that I think is not used nearly enough in gardens is solomon seal. It grows slender stalks that arch over beautifully. The native one is a spring ephemeral that disappears pretty quickly. There's a hybrid version with white variegated leaves that lasts much longer in the garden and spreads quickly into colonies.
