I should add that the along the fence to the left of the 10' space is a new serviceberry tree (about 5 ft high right now) and to the right is a large, existing evergreen.

My math says to plant 2 -- one 3.5' feet to the right of the serviceberry tree and one 6.5' to the right of the serviceberry tree. This would place them 3' apart. I know it is close but my goal is to block the view of the road behind us.

they really arent blue .. if that matters ...

two in 10 feet is about right ...

i am a visual guy ... be nice to have a pic or two ... to understand it all ...

If you want to block the road put up a fence that will do that or at least plant some evergreen plants (preferably both). You are trying to do it all with shrubs because the existing fence doesn't do any screening, and because you are choosing shrubs that will be bare sticks all winter you will only have screening part of the year.

The Hibiscus in particular is unusually late to leaf out and pretty quick to shut down in the fall.

Our HOA will not allow fences (very common where we live). We have
evergreens all along the rest of the split-rail fence so I want some
color. I am ok with the leaves falling off --- the fence is pretty far
back from my house.

Here is the first are a-- about 10' of planting space between the new Serviceberry tree on the left and the existing everygreen on the right. About 5 feet behind the new (tiny) Annabelle hydrangeas.

Plan calls for two ROS here too.

two is fine on the street side.. one to the left ...

why all of one kind of plant???

if i had 3 spots.. i would be looking for 3 things.. that flower at different moments in time ... of differing textures ... and color.. even if just a different green ...

will they all be large transplants like the other???

i think you are doing it too much like throw pillows on the couch and chairs ....

Ken -- suggestions? Landscaper gave Viburnum, forsethia and dogwood (yellow variegated).

I really don't want anything that blooms white because they will be behind the Annabelle hydrangeas.

Most viburnums will have bloomed and be done by the time the Annabelles bloom. And with viburnums, you'll have berries and a little fall color, depending on the variety.

Do viburnums only bloom white?

Mostly, but there are pink cultivars also.
