Description & Identification

E. dubium shares certain characteristics in common with other Eutrochium species, including being a normally unbranched perennial with multiple stems from a short-rhizomatous rootstock, having whorled or rarely opposite leaves, and a pinkish-to-purple inflorescence.

E. dubium is distinguished from other Eutrochium species primarily by its triple-veined leaves and smaller max height; other features can be used to distinguish between other, specific species.

Habitat

Found on moist, acidic soils, usually in sandy soil but sometimes in other soil types. Can tolerate soils with some gravel and clay. Habitats include bogs, marshes, swales, sunnier spots in swamps, and low-lying streamsides and river banks in the coastal plain.

Tolerates some salinity and drought.

Uses

Widely used as an ornamental plant in gardens and landscaping, where it is valued for its tolerance of wet and poorly-drained conditions. Several cultivars exist, the best-known of which are 'Little Joe' and 'Baby Joe'. These and most other cultivars have been selected to have a shorter maximum height even in rich soils, and better tolerance of typical garden conditions, including greater drought tolerance.
