You want late-spring blue flowers.
You are planting in groups.
Skip This If
The soil dries out hard.
You need summer-long bloom.
You need a short edging plant.
PGNE Report Card
Category
Grade
Why
Landscape Impact
B+
It gives a strong late-spring blue accent and tidy vertical texture, but one plant alone can look thin.
Growth Rate
A-
It fills in quickly for a clumping perennial without acting like a running groundcover.
Maintenance
B
Maintenance is straightforward if the soil stays moist, with cleanup and division as the main chores.
Deer Resistance
A-
Deer usually pass this by, since the foliage deters browsing, though no plant is completely immune where pressure is severe.
Small Space Fit
B
The clumping habit fits mixed beds, though it reads best with a little room to repeat.
Our Experience
At PGNE, we'd typically recommend Caesar's Brother in repeating groups near daylilies, sedum, or other later bloomers so the spring flower show is supported after bloom by tidy foliage.

Customers Usually Ask
Does it need wet soil?
Not standing water, but it does best where soil stays consistently moist.
Will it bloom all summer?
No, the main show is late spring, so pair it with summer bloomers.
Can I cut the flowers?
Yes, the stems work well for cutting when blooms are opening.
Why Choose Perennials for Your Garden?
Return Year After Year: Perennials come back each season, reducing replanting costs while increasing garden maturity
Extended Seasonal Interest: With proper selection, you can enjoy continuous blooms from spring through fall.
Low Long-Term Maintenance: Once established, many perennials require minimal upkeep and become more resilient over time.
The Pro Growers of New England Advantage — Perennials
Perennials bring dependable color, texture, and seasonal interest to your landscape year after year. At Pro Growers of New England, our perennials are grown locally and selected for reliable performance in New England’s soil, temperature swings, and growing conditions.
We welcome customers to visit the nursery, explore our selection in person, and choose healthy, well-developed plants with confidence. When you purchase perennials from PGNE, you’re investing in locally grown varieties chosen for longevity, repeat bloom performance, and long-term garden success.
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!
