Dwarf trees/evergreens for foundation plantings
I am from central NJ and trying to plan my foundation plants. This post has perhaps too many questions.
I have a difficult space to work in. The beds are narrow but very deep so I need to layer the plantings. (15w x 18d)
I'm considering dwarf conifers and perhaps some small trees.
I came across some grafted varieties of plants that seemed very nice but I'm not sure of the habits of grafted shrubs and conifers.
A web site called JCBakker.com has many interesting varieties of grafted trees and shrubs.
Weeping pear, Ginkgo, Viburnum, Rose of Sharon and of course Hydrangea.
Is there anything I should be aware of when considering a grafted plant?
In addition to the small tree I am seeking a narrow pyramid shaped evergreen for interest
and don't want to use the typical Alberta Spruce. It must be narrow, not more than 3 - 4 ft in diameter.
Here are some shrubs/evergreens I've considered:
Narrow Pyramid shape:
Boxwood: Fastigiata, Dee Runk, Graham Blandy
Alberta Spruce: Jean Dilly Dwarf, Blue Dwarf
Juniper: Blue Arrow
Viburnum, Rose of Sharon, Barberry, Hydrangea,
Small Dogwoods: ?
I've also considered a Weeping Red Maple for a small tree, and a dwarf crab apple but the flowers don't last long enough so I prefer the dogwood.
Any suggestions would be welcome.
