Choose Diabolo® Ninebark Tree Form if you want dark foliage in a tight ornamental-tree spot without waiting on a slow maple. The tradeoff is pruning: the grafted canopy needs shaping so it stays balanced and does not get crowded.
Buy This If
You want dark foliage contrast.
You need a small ornamental accent.
You can prune once or twice yearly.
Skip This If
You want a natural shrub form.
You need a solid screen.
Deer pressure is heavy and unprotected.
PGNE Report Card
Category
Grade
Why
Landscape Impact
A-
The dark foliage gives strong contrast, especially against green foundation plantings or light siding.
Growth Rate
B+
It fills in quicker than many ornamental trees, but fast growth means more correction pruning.
Maintenance
B-
The tree form needs periodic canopy thinning and sucker cleanup to keep the grafted shape neat.
Deer Resistance
B+
Deer tend to leave this tree alone, though young plants can be browsed or rubbed where pressure is heavy.
Small Space Fit
B
It works in smaller beds when given breathing room, but the canopy is not narrow.
Screening Value
D
It is a focal-point tree, not a privacy screen, because the canopy is raised and open beneath.
Our Experience
At PGNE, we'd typically recommend this for a front bed that needs contrast, not for a spot where the homeowner wants to plant it and never touch it again.

Customers Usually Ask
Will it stay tree-shaped?
Yes, if you remove lower suckers and lightly thin the canopy as it grows.
Does the leaf color fade?
Color is strongest in brighter exposure and can look greener in too much shade.
Is it good by a front door?
Yes, if the bed has room for the canopy and you can prune lightly each year.
Why Trees Are a Lasting Investment
Trees bring structure, shade, and long-term value to any landscape. From flowering ornamentals to strong canopy trees, they define property lines, create privacy, and provide cooling relief during the summer months. Over time, trees grow into the most impactful and permanent feature of a landscape, adding both beauty and property value.
Shade & Energy Efficiency - Mature trees reduce summer heat, lower cooling costs, and create comfortable outdoor living spaces.
Long-Term Property - Value Established trees significantly increase curb appeal and overall home value.
Year-Round Landscape - Impact From spring growth to fall color and winter structure, trees provide continuous seasonal interest.
They're very "leggy" right now but that's not unexpected in the fall. Otherwise, they look healthy, and we're looking forward to seeing them next year.
Showed up on time and planted it perfectly. I indicated a light we had to illuminate it and they placed it for optimal lighting. Worked fast and left a clean worksite. First rate!

They delivered three trees: a big linden, a big poplar and a little spice bush with install on the big trees. The install guys were great and professional and fast. All the trees looked good with minimal damage.

I went up there today from Quincy MA to pick up two Blue Wichita Junipers and they were absolutely beautiful. Thank you, Chris and everybody from Pro Growers of New England!

The plants are beautiful and all 13 were consistent in height and width. And at a fraction of the cost of other garden centers. Having the team that delivered them do the planting was one of the best values I can think of. They did a great job from start to finish and even helped me with my watering system which they didn’t have to do!
