In the North, we tend to think of bromeliads as somewhat rare and exotic. In Brazil, this one grows on trees. The most notable feature of Quesnelia marmorata, or Grecian urn, is its foliage. The tall, narrow leaves have mottled horizontal bands of green and white and curve outwards gracefully at the top, like the lip of a vase. The bloom, though short-lived, is lovely, with pinkish maroon bracts that open to reveal lavender-blue flowers.
