About the Speaker
Alan Petravich grew up on a dairy farm in Pine Grove, PA. Both his BS in Biology and Master’s in Horticulture are from Penn State. His thesis work dealt with height control of herbaceous perennials using paclobutrazol and DIF. Other projects in graduate school included studies with fiber pots, which were impregnated with Spinout, to improve root structure. After receiving his undergraduate degree he headed to sunny California and spent several months working at Disneyland as an attraction host on the Undersea Voyage. After graduate school, and before coming to Longwood, Alan was a grower for Trail Gardens in Pottsville, PA. At Trail Gardens he grew annuals, perennials and Poinsettias. He has been at Longwood for 16 years where he trials a variety of plants from around the world for displays both indoors and outdoors. He is constantly amazed by the variety of plants that pass through his greenhouses. He also conducts breeding work on Clivia and Cannas. In the tissue culture lab, his efforts include virus elimination procedures on Chrysanthemums and Cannas in testubes. From this work, he maintains a bank of clean mum stock for Longwood’s Chrysanthemum displays. Alan also teaches plant propagation classes for the continuing education program at Longwood and has led Moonlight Magic walk in the gardens. Alan is president of the North American Clivia Society.
