You will need to provide more information about where in the world you are located, the specific site conditions like sun exposure and what your expectations from this landscape are to get useful plant suggestions.

Thanks @Christopher CNC. Had added that we are in Zone 6 (Boston suburbs). Given the trees beyond the wall, there will be partial sun exposure. My expectations are to have a low maintenance landscape and create a nice view from patio and driveway.

Lowest maintenance and very attractive would be Geranium macrorrhizum (mostly shade) or its close relative G. 'Biokovo' if there's mostly sun. Since the area is quite large, you might try one section in that and another in Chrysogonum 'Eco Lacquered Spider'--both would be evergreen in your zone.

Once they are established, there would be only very occasional weeds. And no further maintenance.

Do you have deer? Hostas could be nice, also mountain laurel (kalmia latifolia). Agree a forest landscape would be attractive. You could plant daffodils this fall for color next spring.

No garden is no maintenance, but avoid things that require extensive pruning and spraying (like roses).

I think a mix of ferns and other evergreen ground covers are your best bet L love ferns and vinca mixed I have vinca all under my pine and cedar trees it is pretty all the time and gets little purple flower in the spring. I has nice glossy green leaves and needs very little care and the ferns the same. I have planted bulbs in one area where I have vinca and they do quite well but I need to go and get rid of the dead stuff each year. Vinca is invasive but IMO that is not a bad thing where you are using it.

Thanks everyone for your great suggestions. Forgot to add that our plot ends 14 fet beyond the wall. In addition to fern and ground cover, any ideas on colorful perennials? I have noted down ‘Geranium macrorrhizum ’ , 'Eco Lacquered Spider’,

‘rhododendron’.

@latifolia we do get deers, turkeys and occassionally fox.

Given the steepness of the terrain and the very large amount of hardscape, I would focus on the possibility of excessive rain and run-off and making sure whatever you design and plant helps keep the ground stable and redirects water away from these walls and house. Also, there are many attractive plants that discourage ticks, and deer --- while some absolutely attract them. You definitely want to discourage them living near you, so get advice from neighbors and local nursery/landscape pros. If you go walking in that area, be sure to use lots of tick protection. If you don't know about ticks, be sure to read up on them today and what you need to do to protect your family and pets. Tick season is right now and will remain very strong until the snow falls.

Some option

No to vinca. It's invasive. If your soil is acidic enough, you can do lowbush blueberry. Otherwise, bearberry or wintergreen make nice groundcovers. For shrubs, I second Mt. Laurel and add in Itea Virginica. Woodland phlox and Tiarella make good groundcovers, too.

Creeping red fescue like Jasper 2 if you can find it is a ground cover grass. It grows and falls over at about 8" to form soft 3D clumps. Good in shade and doesn't need watering. It's considered no mow.

People have to get real about animal life in Massachusetts. You don't plant things like wild blueberries around your house. Also, even if you have five stories of cement between the woods and your house, you don't plant invasives in the neighborhood.

There are plenty of ecology minded local landscapers you can consult to tell you how to plant for your neck of the woods, to keep your house safe, your family safe, your neighbors happy (if not necessarily the bears, fox and deer, none of whom you want to be feeding).

Thanks Celery. Visualization, Rendering images for the image. Any other options? :)

Thank you for your comments and suggestions dan1888 mytwo cents Sigrid Patricia Colwell Consulting latifolia Kendrah laceyvail 6A, WV

Check out White Flower Farms. They list deer resistant plants. Peonies are long lived and provide beautiful blooms, but pretty bare in winter.

How voracious are your deer? You added that comment as an after thought, but if you have frequent deer visits it needs to be the first consideration in choosing plants or you could end up wasting a lot of $!

There are low growing flowering shrubs that are very deer resistant - deutzia, potentilla, spirea (Blue Kazoo white is a good one). My favorite plant for edging/ground cover is Epimedium Sulphureum, which deer don’t touch. It has airy (but inconsequential) yellow flowers in spring, but nice dark green heart-shaped leaves.

I keep seeing plants labeled “deer resistant” that our voracious deer eat in a flash. The two sites below do have good info that you can count on.

Check out the lists of deer-resistant shrubs and perennials at the Proven Winners site:

Also an excellent site that rates plants by deer resistance is the Rutgers University site: https://njaes.rutgers.edu/deer-resistant-plants

A good local nursery should be able to help with choices.

Thanks @chloe00s for your feedback and the links, very helpful.

In terms of voracious, I do see them eating plants when they come by. Probably less than 10 times a year as far as I can recall. Sorry, I should have mentioned it in my original post about the animals.

Trust me, your deer are voracious, especially if MA stops having mild winters and gets some serious cold again. They will want to eat whatever they can find. And even if it stays warm, they will come by more than 10 times a year if you start planting things they like to eat!. ;)

Here are a few ideas:
