And you don't. Just check the living sundial."Our goal is to put our creative hooks into our guests and get them to notice plants and appreciate the plants that surround them," says Joe Parr, Busch Gardens Tampa Bay's director of horticulture. "I am very happy to see guests every day happily snapping family photos in front of our landscape displays."Want to copy his sundial? Joe's instructions:• Choose a sunny, level spot and install a pole to mark the center of your dial.•With a string and stakes, mark each "ray" on the hour as the sun travels across the sky.•Choose a compact, upright, vertical-growing shrub for the gnomon, the central feature that casts the shadow and replaces the pole.•Use full, compact plants that can take regular shearing for the rays — the lines that mark the hours. End each ray with a conically sheared plant.•Fill the spaces between the rays with annual bedding plants, using contrasting colors in each section.Tip: Between roller coasters and shows, check out Busch Gardens' inventive plant displays.No need for rain: These daisies bloom perpetuallyEven during the hottest, driest months — coming in May! — Bill Carr's daisies never droop.They're made by Amy and Joe Hines of Pensacola (rustables.wordpress.com) from recycled automobile parts."I was really impressed with their work, which is on display at Leu Gardens among other places," says Bill, who lives in Plant City.
