Walking through the maze of plants at Joshua's immediately slows the heart rate, as you lose yourself in a mini-Garden of Eden. Two zebra finches, Dot and Dash, hold court in a faux bois birdcage, stuttering the soothing Morse code that inspired their names. We've seen Joshua Kornegay throw in an extra herb plant, say, as a lagniappe, and his generosity extends to his time as well. If you don't learn all you need to from his helpful notes on each plant, he or right-hand man Joel Rangel will fill you in. "If it's hard to grow, I write, 'Hard to grow,'" Joshua says.
