Prairie Garden has split personalities. On the inside, it resembles a Michael's or other chain craft store, with plastic flora, candles, and cutesy decorative signs you'd find at Grandma's house. Outside, it's a well-organized collection of plants and tools for landscaping, much larger and more exciting than the gardening section at Home Depot.
Overall, I'm pretty impressed by the diversity of houseplant accessories sold here. During the summer, a few rooms are packed with colorful pots great for both indoor and outdoor settings. There are a few shelves reserved for bonsai enthusiasts, with appropriate containers, decorations, and tools. Different types of general potting mixes and substrates can be purchased for an assortment of plants (orchids, indoor starters, etc.).
The store is stocked with plenty of craft supplies for creative home projects. For example, I like their assortment of Vintage-style bird cages, which can be used as shelters for indoor plants (great for protecting plants from mischievous cats). I've also bought fish bowls and decorative rocks to construct my own terrariums (miniature gardens).
Only 2 things really bother me about this place. First, houseplants and their associated products (though kept indoors year-round) are only sold during the summer. By mid-September, all of these plants and plant-care items are replaced by holiday merchandise, which is pretty annoying if you need a replacement pot or some additional potting mix.
Second, a lot of their gardening experts, though good at answering general questions, could not provide feedback on certain specific issues (e.g., "I bought this plant last week, and it developed 'X' problem with its leaves. Do you know what's wrong and how I can fix it?").
