Description

Eutrochium maculatum

Also known as:

spotted Joe Pye weed

,

spotted Joe-Pye-weed

,

spotted trumpetweed

Scientific Synonyms:

Eupatoriadelphus maculatus, Eupatorium maculatum, Eupatorium purpureum var. maculatum

Description

Eutrochium maculatum is a rigid, tall growing wildflower, easily reaching a height of 6'. It can be differentiated from other Joe Pye weeds, by the purple spots on its stem, hence the common names. It produces huge, domed clusters of pinkish, purplish, fragrant flowers.

Cultivation

To reach its full potential, this species of Joe Pye weed requires a very wet environment and partial sun. It thrives with wet feet, and can be subject to irregular, or seasonal inundation. I can be used in dryer locations, provided the soil remains consistently moist, particularly during the hot summer months, or if planted in full sun (full sun will produce more flowers, but a shorter plant). This is an ideal species for use around water features, where its sheer size will create an impressive presence. It will self seed readily but with low germination rates. It colonizes primarily by its fibrous, rhizomatous roots. A late summer bloomer: July to September. Cold hardy: zones 3-6

Propagation

Easily propagated by division in early spring. Can also be propagated from seed. They should be sown thickly, as germination rates are low. Stored seeds will require up to 3 months of cold-moist stratification, to improve germination rates.

Additional Notes

Eutrochium maculatum is sometimes confused with Eutrochium purpureum (purple Joe Pye weed). The former's stems are often entirely purple, whereas the latter only has purple at the nodes.
