You want bees and butterflies.
Skip This If
You need a tidy box-shaped shrub.
Your soil dries out fast.
You need winter screening.
PGNE Report Card
Category
Grade
Why
Landscape Impact
B+
The white flower spikes and fragrance carry well in summer, especially near patios, paths, or entries.
Growth Rate
B
It fills in at a steady pace but will not give instant mass the first season.
Maintenance
B+
Pruning is usually light, mainly removing stray stems or shaping after bloom if needed.
Deer Resistance
B+
Deer tend to leave this alone, though hungry deer may sample it where pressure is heavy.
Small Space Fit
B-
It can work in smaller beds if given breathing room, but it is not a tight little edging plant.
Screening Value
C+
It adds summer bulk and foliage but drops leaves and should not be counted on for privacy.
Our Experience
At PGNE, we'd typically recommend this for moist, partly shaded beds where customers want fragrance, native value, and pollinator activity without fussing over a formal shape.

Customers Usually Ask
Does it need wet soil?
No, but it does best with consistent moisture and struggles in dry spots.
Will it bloom in part shade?
Yes, though more sun usually means heavier flowering if moisture is available.
Is it good near a patio?
Yes, that is one of the better uses because the fragrance is noticeable up close.
Why Clethra (Summersweet) Belongs in Your Landscape
Fragrant Summer Blooms - Sweetly scented flower spikes bloom in mid-to-late summer when most other shrubs have finished flowering
Thrives Where Others Struggle - Tolerates wet soil, shade, and even coastal salt spray better than most ornamental shrubs
Pollinator Favorite - Attracts bees, butterflies, and hummingbirds throughout its long bloom window
Grown and hardened off for New England conditions
We grow and acclimate our Proven Winners stock right here in New Hampshire, so it's ready for New England winters before it ever leaves our nursery.
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!
