Fragrant White Blooms Meet Compact Growth

Why Summersweet Clethra Shrubs?

Also known as Hummingbird Summersweet, this shrub produces fragrant, white blooms that merge with the promise of richly-hued green growth, delivering contrast that's second to none. And this deciduous favorite lives up to its name, attracting graceful wildlife that gives you the most elegant yard on the block.

From mixed borders along your driveway to perennial plantings in your flower beds, the Summersweet stands out...even in wet, swamp-like areas. Unlike similar ornamental varieties, the Summersweet stands up to tough conditions, thriving in a compact growth habit that's well-suited to tight spaces, poor soil conditions and even cold fronts down to -20 degrees. That means you get summertime flowers and vivid autumnal colors for a show that lasts nearly year-round.

Shipped Well

The three plants arrived well, about 6” tall, with leaves and good roots. A week later, they are thriving, even with high heat. I’m looking forward to see them fill out and add beautiful color to my front flower bed.

Small and healthy, potted in deep 1 qt containers

Five healthy plants with lots of new growth arrived today. I appreciate the availability of quart-sized plants, so I can dig them in around the roots of a large hickory tree (which is limbed high, so there’s plenty of light).

Fast Growing Trees Plant ExpertHi Karen, five healthy plants with lots of new growth on arrival is just wonderful! What a thoughtful planting spot around the hickory tree roots with plenty of light. Summersweet Clethra is such a beautiful and fragrant variety and we think they're going to fill in and thrive beautifully in that spot. We're always here if you need anything along the way!

healthy

Small but healthy! look forward to seeing them fill in a large bed.

Fast Growing Trees Plant ExpertHi Mary, small and healthy is a perfect start! Just to reassure you, your Summersweet Clethra is exactly where it should be at its current age and is all set up for success. As a nursery we take care of these younger plants until they're ready to go to their new forever homes and just ask for a bit of patience to let them spread their roots and start growing. We think they're going to fill in that bed beautifully!

So far, So good!

Although pretty small, the plants arrived looking great. They've been in the ground for a week now and are still looking strong.

Little fella

Experience was great plant arrived nice and healthy planted him in the ground. He’s growing. I still don’t have any flowers on him yet but you know he’s a little guy are still some for this summer.

Fast Growing Trees Plant ExpertWe're so glad your Summersweet Clethra arrived healthy and is growing, Linda! No blooms yet is completely normal for a young shrub settling in. Give your little guy time and those gorgeous fragrant flowers are on their way. We're rooting for him!
