Why are Callery Pears Pretty AWFUL?

For several years ISAC and various Soil & Water Conservation Districts have worked to spread the word on the invasive nature of Callery Pear, sometimes called Bradford Pear.

What is Callery Pear?

Callery Pear is an popular ornamental tree that has been widely planted for its fast growth and showy spring flowers.


It is also called Bradford Pear, after its first cultivar (or cultivated variety).  

All ornamental pear trees are considered callery pears; some of the other cultivars include Aristocrat, Cleveland Select, Autumn Blaze, and Capital.  

Identify, Control, & Report!

Why Shouldn't I Plant It?

While callery pears have been widely planted, the creation of multiple cultivars has allowed the once sterile trees to start producing abundant fruit.  This fruit is eaten by birds that carry the seeds across the landscape, allowing callery pears to invade natural areas.

Now an aggressive invasive, callery pears form dense thickets, displace native plants, degrade wildlife habitat, and cause problems along roadsides.

They can also pose a safety hazard as their poor structure causes the trees to split easily.

An easy way to help slow the spread of callery pear is to remove them from our landscaping!

What About Native Alternatives?

While there are many non-invasive alternatives to using Callery Pear, many people are opting to replace them with native landscape trees.

Native plants are not only beautiful, but also benefit birds and other wildlife.  Unlike non-native species, these plants support multiple pollinators and insects, providing food for Indiana birds.  

Unlike invasives, if native plants spread from your yard to nearby natural areas, they don't harm the ecosystems.
