They bloom in mountain meadows, woodlands, prairies, even the driest deserts - wildflowers are vibrant but ephemeral beauties, embellishing landscapes with strokes of colour before disappearing for another year. With a dozen photographs that capture wildflowers in their native environments, this calendar is a tribute to North America's loveliest blooms. Beds of Dune Evening Primrose spread over a sandy California desert. Yellow Arnica and pink Monkey flower grow unrestrained in a Montana field. And ethereal purple Pasque flowers herald spring in the Arctic National Wildlife Refuge. It's pure artistry by nature's hand.
