Pacific Ninebark can tolerate dry conditions, but grows best in moist areas making it a great choice for rain gardens that are often dry in the summers, but wet throughout fall and winter. Its root system and large thicket forming nature can provide excellent stability for erosion control. Ninebark is great at attracting pollinators due to its large size and prolific small cluster flowers, that allow bees and butterflies to efficiently move form flower to flower.
