On my recent roadtrip through PA (that's Pennsylvania, USA), I stopped at Terrain- this had been on my list for a long time. It is one hours drive from Philadelphia & well worth hitting around lunchtime- make sure you book a table at their internal cafe, Styer's.
The shop & cafe are surrounded by gardens, a greenhouse for the more sensitive plants, an open wood fire pit, trees, wood walls, grasses, produce, seedlings & other gardening essentials and after recent snowstorms in the East coast region (I know- snow for Halloween!)- it looked all magical & Narnia-esque.
As you meander toward the cafe: books, twine, gardening tools, lights, furniture & uber-cool products are for sale plus great storage & display ideas are a-plenty ie jars of honey & it's own comb casually displayed on a window (heaven!).
The cafe is a conservatory of zinc potted green walls, overflowing log shaped planters, floating string balls (you know the ones with the trees), all light & bright & split bamboo shaded. The food is seasonal, local, fresh as it should be & feel free to BYO champagne or a drink of your choice as they are yet to be licensed but happy to pop your cork.
Even the bathrooms are considered & inspirational. NB: take your camera!!
