With the Chelsea Flower Show just wrapping up in London, flowers have been on my mind -- especially the one named after Helen Mirren, which must look great in a bikini. It seems there’s a new trend in travel called “Garden Tourism,” where people plan their vacations around flower shows and famous outdoor destinations. On the one hand, this sounds like the kind of thing my mom would decide was fun and drag us kids to, and we’d intone, “Ohhh, a flower. Oh, another flower. Oh, another flower,” 'til she grabbed us by the scruffs of our necks and threw us back into the car, resolving aloud never to try anything creative ever, ever again. On the other hand, it seems cities are changing the nature of these kinds of attractions so they’re more about eco-tourism, loving nature, and learning more about ecology, which sort of brings into question the wisdom of taking a plane to see one, but ... anyway.
