A good garden center has the inside info on the plants and plans that will make your outdoor space thrive. The opinions we collected from area consumers on garden centers they use, reported on our Ratings Tables, will help you find the best places to shop. You'll find that some stores were rated “superior” overall by at least 80 percent of their surveyed customers, but several other retailers were rated “superior” on this question by 30 percent or fewer.

Fred Meyer, Home Depot, and Lowe’s scored, on average, lower than almost all the other stores.

But for the selection of plants they sell, these three big chains did very well on price. Fred Meyer’s prices averaged 33 percent below the all-store average for comparable items, Lowe’s averaged 20 percent below the all-store average, and Home Depot’s 15 percent lower.

Though it’s not the case with most types of services and stores we examine, paying more for plants at garden centers slightly improves your odds of getting better advice, service, and plants. Many of the stores rated highest for quality charge higher-than-average prices, but some outlets evaluated on Ratings Tables that rate high for quality also have below-average prices.

For specific plants, we found enormous nursery-to-nursery price differences. For example, for a creeping rosemary in a #1 container, prices ranged from $4.99 to $14.99; and for a sansevieria in an eight-inch pot, prices ranged from $19.99 to $50.
