False spirea (Sorbaria sorbifolia) is beginning to bloom. Not much information about this plant is found beyond gardening websites, but it may be a species to watch in the Adirondack region. Why is there cause for concern? False spirea is an ornamental plant available for home gardens, but populations have been found growing in dense monocultures in natural areas. Stands of the plant are near Lampson Falls along the Grasse River, along the west branch of the Ausable River near the ski jumps in Lake Placid, and along the east branch of the Ausable River near Marcy Field in the Town of Keene. All are found outside of cultivation, and their proximity to water makes dispersal of seeds easy and uncontrolled.
