You'll have a jungle if you don't do something deliberate. Otherwise you'll have pioneer species moving in to try to get the soil ready for other species.

What about adding some acid loving bushes that grow BIG like rhododendron/azalea or hydrangea?

Add some lush ferns

And hostas are another classic choice

You could do a low dry-stacked stone wall along the roadside (check local setback requirements) and around the corner into the driveway, seeding small scale flowers like forget-me-not and periwinkle in front of it, on the road side. I would keep it low, no higher than knee height since it is neither for security nor for a retaining type wall.

thank you for your response. ferns are a good idea i can probably transplant some that are encroaching in the back. i have rhododendron all along the side i added to the blueberry patch today i have the canopy and understory but it needs to grow in. You are right if i dont manage it it will look like hell. I will mow and build slowly i was trying to be lazy. i love the idea of a rustic stone wall defining the driveway edge. you can see where they widened it under the pines, im pushing it back. spent today shop vacing gravel the neighbors must think im nuts :) my goal is to just hide the house a bit most houses here are set deeper and I didnt need an 8 car driveway. thanks for your thoughts.

I would definitely create a distinct line (bed line) that separates the mowed lawn from all other planted things (beds.) Kill the weeds in the beds and allow the intentional plants, trees and shrubs, to remain. Mulch the beds heavily to suppress weeds. Eventually, you'll get them under control. If you didn't mow, while you'd have the eye-level screen you desire, it would be a messy eye sore to those with civilized standards. It would be relatively easy to maintain a heavily mulched area and allow it to fill in with whatever plants you want over time.

In a bed that size in a casual rural planting, I don’t mulch. I honestly spend 2-3 hours over the course of the season weeding and don’t generally worry about distinct bed lines, though if you want a more finished and less casual look, do edge it. The shade along with the groundcovers reduces weeds, so I really don’t have to mow or put in a lot of effort.

@NHBabs(4b-5aNH) how much ground does your partridge berry cover? I have tiny bits I'm transplanting, but nowhere in Maine do I see more than small patches. I've seen less wintergreen, but the same question holds.

My largest patches of partidgeberry are perhaps 5’ across. Wintergreen and low bush blueberry grow intermingled along a swath of roadside perhaps 25’ wide and 1/8 mile long. Both occur other spots also, but that is the largest. My soil is very acid, fine sandy loam without a ton of organic matter except where I have added it. The partridge berry likes a lot of shade, but both the blueberry and the wintergreen grow best in at least a half day of sun here. I would say the large patches are more than 30 years old since they were here when we moved in 20+ years ago, though I have removed competitors to encourage them.

well i mowed because it looked like trash. I still have to figure out how to manage until the shrubs and trees grow in.
NHBabs I think ground cover will be the answer until the plantings grow in I definitely dont want to deal with defined edges the rest of the propery the lawn is just mowed up to the woods edge where wild blackberry and other low shrubs take over. I want it too look more natural in front too. I will have to go in stages as this years time for big moves is over. Im still not sure how to manage it until things grow in, mowing around the shrubs is annoying. I also need to deal with the driveway unlike the grass that earth is compacted. In the fall maybe ill kill the grass and start something.

I have a summer place with plenty of woods. There are a lot of tiny, native groundcovers around the edges, the partridge berry, some wintergreen and plenty of native wild strawberries (they are tasty, if you can beat the critters to them, but about the size of a pinhead, so you don't actually taste much) They are small, so you have to look, then look up what you have. In with the natives, I have vinca and speedwell, both of which are invasive nonnatives.
