High tunnels are unheated plastic-covered structures used in the horticulture industry to advance or extend the harvest season of high value crops. In Iowa, these polyethylenecovered structures provide a level of environmental protection between a heated greenhouse and open field production. Without supplemental heat, high tunnels in Iowa will not support annual crop growth and production between November and April, thus most high tunnels are not used during this cold season. In late October 2008, a study was initiated at the ISU Armstrong Research Farm to evaluate the potential of growing tulips as a cut flower crop to fill in this production gap and provide for year-round production in an unheated Iowa high tunnel. A second objective of the study was to control tulip bloom time in a high tunnel through variety selection, planting depth, and row covers.
