Lenten Rose

Mike Dana, Professor, Horticulture & Landscape Architecture, Purdue University

This “evergreen” Lenten Rose, Helleborus orientalis in West Lafayette, shows the effects of the winter just ending with temperatures reaching into the lower teens below zero and prolonged periods of cold, drying conditions.  The “scorched” foliage will soon give way to flowers followed by new foliage. 

This plant is truly evergreen in a mild location such as Seattle, or the British Isles, but often suffers in this manner in the harsh Indiana winter. The rootstock, however, is hardy enough to survive, so we grow it as a deciduous herbaceous perennial rather than a broadleaf evergreen herbaceous perennial.
