Garden tours are an adventure of color and shape, for nature lovers, photographers, and, of course, gardeners, who combine green thumbs with green travels.
Perhaps the most famous spring garden is Keukenhof Gardens, one hour from Amsterdam, that blooms with more than seven million tulips, in nearly as many colors. Some of these blooms are rarely seen outside the garden's gates. Seven million tulips. It boggles the mind.
Back to the flower festivals -- pardon the pun, but they are blooming everywhere in botanical gardens. Nearly every city of any size has one.
Ah, the flowers that bloom in the spring. Tra la. Definitely great green travel.
