B. Lockhart, D. Mollov, and J. Voth-Hulshout

October 2012


Spireas (Spiraea spp.) are woody perennial ornamentals that are widely grown throughout Minnesota and in other states due to their cold hardiness and adaptability to a variety of low-maintenance landscape settings. Spirea stunt phytoplasma was first identified in S. tomentosa in central New York. This is the first report of its occurrence in non-native Spiraea spp. (S. japonica, S. × bumalda), and in Minnesota.
