What's that smell? Bradford pear trees are blooming in OKC — here's what to know

If you've lived in Oklahoma City at some point during springtime, you've probably encountered — or at least smelled — the pungent blooms of the Bradford pear tree.

In 2017, we put the Bradford pear tree, an ornamental tree originating from Asia, on our list of Oklahoma's five most hated trees — but what exactly has been drawing the ire? Its odor while blooming has been described as rotting fish, urine and baby poop. The tree is considered invasive, leading to bans in at least one state. The tree does have some local fans who say the hate is misplaced, however.

Here are a few things you should know about the Bradford pear tree.

Where did the Bradford pear tree come from?

According to USA TODAY, the Bradford pear tree was introduced to the U.S. in the 1960s from its native Asia. Their popularity grew as they are easy to plant, easy to move, and easy to maintain, and they're most frequently found on the East Coast, and most commonly planted in South Carolina.

Yes, they're considered invasive

The trees were originally thought to be sterile, but as they were planted in the U.S., wild hybrids began to appear. In Oklahoma, wild Bradford pear trees have become invasive, often sprouting up in clumps along fence lines and in fields, according to an earlier Oklahoman report. The wild trees also often have thorns in addition to the smell.

In the fall, the trees attract masses of migrating birds, posing a nuisance and health hazard in public areas.

South Carolina is set to enact a ban on sales of the tree beginning in October 2024. The Oklahoma Invasive Plant Council has the tree on its watchlist for invasive species.

When do Bradford pear trees bloom?

The trees produce white, pungent flowers that typically bloom in the early spring months. The blooms can last for up to two weeks.

Do Bradford pear trees produce fruit?

The original trees were bred to be sterile, but the hybrid, invasive trees do produce fruit. The fruits are not edible to humans, but birds do eat them.

How do I get rid of a Bradford pear tree?

Though they have a shorter lifespan of 20 years, the best way to get rid of a Bradford pear tree is to cut it down — but homeowners are advised to avoid planting the trees to begin with.
