WASHINGTON — When it comes to buying live plants, pinching pennies could cost you.

That’s what Washington Consumers’ Checkbook found when they analyzed more than 100 garden centers in the D.C. region.

“You generally have to pay more to get higher quality products,” says Kevin Brasler, executive editor of Washington Consumers’ Checkbook.

Large chain stores like Home Depot and Lowe’s tend to have lower prices. But Brasler says you can find a larger selection and more knowledgable staff at smaller, independent stores — if you’re ready to pay up.

“Some stores charge prices that are five, even six times higher than their lowest price competitors,” he says.

For the most part, customers are satisfied with the pricey plants.

But what if you get a dud?

“Even the big chains have pretty generous return policies for these things,” Brasler says.

Washington Consumers’ Checkbook is partnering with WTOP to offer their report on more than 100 local garden centers until the end of March. You can find it here.  Just enter your email address in the designated spot.
