Habitat: sunny, damp places

More: Good for pond margins, wet meadows, and bog gardens. Attracts pollinators and its long-blooming flowers are a good nectar source. Deer resistant. This structural but airy perennial won't be for every garden. It is vigorous, and self-seeding may occur. I think these types of plants are excellent for large pots. They can be the focal point in a container arrangement on a patio, for example, and be more manageable than if in a typical border. It is also easier to give them the moisture they prefer. Since this plant is hardy to zone 4, it's a good bet it will winter over in a large pot either outdoors or in an unheated space such as a garage or barn. The flower is a pretty bouquet detail, adding movement and bright vertical pops of color.
