Great selection of annuals, perennials, shrubs, trees, etc. Also sell mulch, pots, benchs, fountains, garden statues, etc. Overall, an excellent garden center. Not the cheapiest around, but they kick Lowe's and Home Depot's butt on their plant selections.
Their staff is extremely helpful and can answer all your questions.
Parking can be a premimum in the Spring, so be warned! I often wander around the place for an hour, just taking everything in.
