Winter-hardy hibiscuses are herbaceous, shrub-like perennials in the mallow (Malvaceae) family that belong to six species native to the United States and southern Canada ( Lawton, 2004 ; Winters, 1970 ). They grow naturally in marshy habitats

A new garden chrysanthemum with the shrub plant habit has been developed by the public sector University of Minnesota Flower Breeding and Genetics program. The program is well known for introducing trendsetting plant traits (winterhardiness, frost
Four winter-hardy strawberry selections and three cultivars where planted in northern Ontario in 2003 in a split-split plot trial where half the rows were mulched and half were left uncovered for the winter. Within each split plot, half the rows were sprayed for tarnished plant bugs and half were not. Yield and tarnish plant bug damage data was collected for two picking years. Two selections maintained their yields in the unmulched plots compared to the mulched plots. Yield for one of these selections was higher in the unmulched plots the first picking year and equal to the mulched plots in the second year. The remaining cultivars and selections produced less when not mulched for the winter. Except for the two selections that maintained their yields in the unmulched plots, plots where straw was applied for the winter had less tarnish plant bug damage. When the plots were sprayed for tarnish plant bugs, damage was reduced for most but not all selections and cultivars.
