It would help if you told folks where you are - nearest large city and hardiness zone.

Do you know what type of hydrangeas or the height they are supposed to reach? Would you consider an evergreen groundcover to fill in around your other plants rather than a row of shrubs?

Sorry I am zone 8b. My hydrangeas are ES Originals.

I would rather have something behind the hydrangeas rather than a ground cover.

Whatever you decide I would urge you not to plant 'rows' of anything and definitely not joining the trees. This is an informal bed.

Ditto on no rows. Groupings are much more attractive.

I am not apposed to groupings at all, where would you place the groupings ?

Arborvitae 'Tom Thumb' doesn't get over three feet tall and is always a perfectly shaped green shrub- look just to the right of the bottle tree. These have been in place since 2008.

These in front are the same age.

before you look at my picture you can not laugh! haha, I did a little work on the computer.. This is the right side of the driveway entrance. On the left side I have three 5ft circular boxwoods with the same hostas that are on this side. I like symmetry and for that reason I had thought, why not bring the boxwoods over to the right side as well ? So I came up with a quick little picture to show where I would add the new plants.

1. I added the daylilies to the left side of this garden bed, because I will be doing that anyway and it helps in the picture

2. I added 4 dwarf boxwoods in a circular design in the back row.

3. I added liriope in between the boxwoods as a filler that wont get too tall and block my view.

I feel like this might be a good compromise between having some evergreen and not being too large so it blocks my view from the porch, but stil adds depth to the garden area.

Any thoughts?

Do I count 7 Hydrangeas? They are going to fill up a lot of your space when they get nearer their mature size.

You still seem stuck on symmetrical arrangements (alternate box and Liriope). The space is irregular and informal - you could certainly balance the two sides of the drive but that doesn't mean they need to be symmetrical. I'd move the Hostas from a row to a triangle. Then I'd use something temporary around the Hydrangeas until they filled out a bit.

Yea there are 6 and I am sure they will full in, I just get concerned with the spring and fall/winter period when I will have nothing there! hydrangea goes bare, hostas will go away, daylily will go away and the crepe myrtle will go bare.. so I'm just left with liriope.

I agree on my be not having to go with boxwood and hostas but I'm not goo at the design part and yes I do like symmetry but I am very open to other ideas, I just don't know what to do! Haha.

And I agree about the hostas, the picture makes it look more of a line than it is, it is a V shape, it's just an off angle. It could be more of a V but that one hydrangea on the left was a little close so I had to turn the left hosta out a little more than I wanted.

You still didn't say where you live. It makes a huge difference. If in the Southeast, that bed is screaming for something evergreen. You want something with curb appear year-round. I'd suggest putting in camellias as a center focal point, assuming the bed gets some shade (or Fatsia japonica or Gardenia). I'd put in a grouping of three right in the middle (but separated from each other by about 4 or 5 feet) and move everything else around them.

Not sure what 'view' you are trying not to block from the porch. View of the street?

By having something large in the center, there will be two views you want to be aware of. One from the street and one from the porch.

I'd be more prone to put in groupings of plants rather than rows ... for example do a cluster of hostas between what looks like crape myrtle and the mailbox.

It's so hard to tell what's going on and the scale by just one photo and no dimensions.

I have a japonica tree in the background of this picture so that is a good option. Would gardenia look funny behind the hydrangeas ? I love summer blooms so I like the gardenia option but having the japonica would create a good look in early spring.. hmm

I have four gardenias that I had transplanted this spring to a new location. They are doing better now but they were in a very shaded area and got very bare and lost leaves and turned yellow. Would it be too much on the plants if I move them again in the fall ? I think they are the Jubilation Gardenias from Southern Living collection. I am in zone 8b coastal SC

I just noticed they have a couple bloom today and one is very dark green again !! the other three are getting better too.
