Clethra alnifolia 'Ruby Spice'
Choose Ruby Spice Summersweet if you want a native shrub with fragrant pink midsummer flowers for a moist or partly shaded spot. The tradeoff: it is not the tightest foundation shrub and can need shaping after bloom.
Buy This If
You want fragrant pink summer flowers.
Your soil holds some moisture.
You want a native pollinator shrub.
Skip This If
The site dries out often.
You need a narrow evergreen.
Deer browse heavily unprotected.
PGNE Report Card
Category
Grade
Why
Landscape Impact
B+
The pink summer flowers and fragrance make it noticeable when many spring shrubs are finished.
Growth Rate
B
It fills in at a useful pace, especially when moisture is steady.
Maintenance
B
It is not fussy, but older stems may need occasional thinning to keep the plant tidy.
Deer Resistance
B+
Deer tend to leave this alone, though hungry deer may sample it where pressure is heavy.
Small Space Fit
C+
It can work in a medium bed, but it is not the best pick for tight walkways or narrow entries.
Screening Value
C
It adds seasonal bulk, but its deciduous habit and rounded form limit privacy use.
Our Experience
At PGNE, we'd typically recommend Ruby Spice for moist beds where fragrance, pollinators, and midsummer bloom matter more than a clipped, formal shape.

Customers Usually Ask
Does it need wet soil?
No, but it performs best where soil stays evenly moist.
Will it bloom in shade?
Yes, in part shade, though flowering is usually stronger with more sun and enough moisture.
When should I prune it?
Prune after flowering or thin older stems in late winter.
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
Shrubs Grown to Perform in New England
At Pro Growers of New England, our shrubs are grown and maintained locally to perform in true New England conditions. From flowering varieties to evergreen foundation plants, each shrub is properly spaced, pruned, and cared for to develop strong root systems and balanced structure before it ever reaches your landscape.
Unlike large online sellers that ship plants long distances, we invite you to visit our nursery, walk the rows, and inspect the exact shrubs available. You can see the size, health, and fullness in person — ensuring there are no surprises upon delivery.
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!
