I would take away the chairs and everything else from the area. Visitors should be able to find your house using the numbers on your mailbox. Since you live in a wooded area, I would keep any shrub plantings very natural. We don’t know where you live, what is a large city near you, so we know what plants will grow where you are? You can visit a local nursery to see which shrubs they recommend for your growing conditions.

Is it shady or sunny? Because you are in a wooded area, I’m assuming the leaves stay where they fall, so you won’t be weeding or mulching between any plantings. A grouping of native shrubs would look nice, and wouldn’t need any special care once established, except to remove any volunteer tree seedlings around them occasionally. A local nursery should be able to direct you to appropriate choices for your space. Places like big box stores don’t usually have people who know a lot about the plants, you might want to find a regular garden center/ nursery where they will also have a better selection.

I suppose if you hollowed out your logs and drilled drainage holes for the excess water, you could plant in them, but the ones you picture don’t look like good candidates. Some pots would probably be easier. Do you have a convenient way to water them if you plant annuals? They might need water every day or two. Otherwise, consider some easy perennials in the ground around the mailbox that won’t need much care once they are established.

I think you need to show us when stuff is in bloom.
