Why the Cumulus Serviceberry?

Cumulus Serviceberry is what we at Bower & Branch call a “window tree.” You’ll want to have this one right outside your window so you won’t miss a minute of the show. In early spring, the aptly named Cumulus will treat you to a cloudlike display of delicate white flowers that sparkle in the sunshine. In summer, the blossoms will have transformed into plump purple-black berries, and songbirds will swoop in for an easy meal. In autumn, the show will continue with ravishing fall foliage that ranges from golden-orange to russet-red. Each season will bring a new act to the stage, and the performance will only get better with each passing year!

Serviceberry is one of those plants that is right under your nose, and you don’t even know it. There are species native to every state in the U.S. except Hawaii, yet few people are familiar with any of them. Most Serviceberries are large suckering shrubs or small multi-stemmed trees. Many years ago, William Flemer, III of Princeton Nurseries in New Jersey set out to breed a Serviceberry that didn’t sucker and was more treelike than existing ones. He came up with Cumulus, which he found to not only sucker less and grow in a more upright manner than other selections, but to also grow faster and resist snow and ice loads better with its strong, thick branches. He patented the tree in 1972.

How to use in the landscape?

The birds are fond of the sweet berries of Cumulus Serviceberry, but you may want to keep the fruits for yourself. They taste a little like blueberries, and like blueberries they’re packed with healthy antioxidants. Try them on your morning cereal or use them in pies, pancakes, preserves, muffins, or smoothies.

Why Bower & Branch?

At Bower & Branch, it’s our job to know and grow trees… especially big trees.

- Trusted, Experienced Growers

- Trusted, Knowledgeable Expertise

- Trusted Brand of Quality Trees Across the United States

We do the hard part. Our trees and plants are grown and cared for by only the best, local growers for years before they find their forever home in your landscape. Bower & Branch is known for having hard-to-find, substantial sizes and selection. The quality of our trees and plants are consistent in health and vigor—always ready for immediate impact in your garden and instant curb appeal. We never rush our trees to reach a ‘grade size.’ Our trees are grown for quality height, vigor, health and age.

We believe in empowering homeowners with the truth about strong, healthy and structurally sound plants that are grown to perform in the ground after they leave the nursery for home delivery, always fresh inventory from the grower.

How To Plant

Fall color on the Cumulus Serviceberry will be most intense in full sun, but the foliage quality will be best if the tree receives some shade during the hottest part of the day. The soil should be enriched with organic matter, moist but well drained. A generous layer of wood chips or shredded bark mulch will help to hold in moisture and moderate temperatures in the root zone.

How To Water

Cumulus Serviceberry will appreciate regular water during its first few years in the ground and irrigation during long dry spells after it’s established.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer, start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late fall. Continue this for the first three years to get your plant well established.

How To Prune

Due to the compact size, pruning is not necessary. However, prune out suckers promptly if they do appear! Be sure to keep trimmers and other lawn equipment away from the trunk, as the bark of Cumulus—like all Serviceberries—is thin and vulnerable to damage.

How Does Shipping Work?

Bower & Branch Trees, the real BIG trees, don’t fit in a box! Our large trees require expert delivery and care, that means our large trees are shipped on Bower & Branch trucks. We are the only ones who know how to ship our big and bigger trees and plants with tender loving care.

We deliver your trees and plants directly to your driveway or curbside! Ask Bower & Branch about planting services and rates – we'd be happy to assist in installation.

*Big trees, Size XL (A) and bigger, will take approximately 2 to 4 weeks days to be delivered. - Sizes large (AA) and smaller (Treelings) will be shipped directly to your home by a local common carrier in a plant-safe box.

How Does Sizing Work?

The size of our trees have nothing to do with the container size like you may find elsewhere–big doesn't mean just height - it’s also vigor, age, and overall health.. Other online retailers are going to tell you that a plant is a seven gallon, that means nothing to your tree or plant (or you.)

Our trees for sale online are graded on large, x-large, and even bigger sizes. This is because our trees are sized by their age—the higher the letter, the more mature the tree. The age determines the trees’ overall height, size of the trunk and the overall branch density.

All of these characteristics are what you should be looking for when choosing a tree for immediate impact and instant curb appeal. Our extra-large tree and plant sizes are sure to wow you and your neighbors!
