I specialize in Floriculture Physiology with a focus on quantifying the effects of environmental and cultural factors on the production of ornamental greenhouse crops. The U.S floriculture industry is valued at $5 billion/year (wholesale). The major crops are: Poinsettia (65.4 million units), Chrysanthemum (91.6 million units), Zonal Geraniums (63.7 million units), New Guinea Impatiens (30.9 million units), and Bedding Plants (44.4 million units). Poinsettia is the highest valued crop at $260 million annually (wholesale).
