Planting joe pye weed seeds

Strictly speaking, this is not considered an invasive plant in North America, since it is native. (By definition, invasive plants are outsiders that spread unwanted in a non-native location). But when planted in a garden, Joe Pye weed can easily escape into surrounding areas, so it's wise to carefully supervise it. It will quickly spread, both through underground roots and by casting its seeds.

Maintaining consistent soil moisture is key for growing a robust Joe Pye weed. During your plant’s first growing season, keep the soil evenly moist at all times but not soggy. Even after the plant is mature, try not to let the soil remain dry for more than a few days at a time, especially during hot weather. A layer of mulch around your plant will help to retain soil moisture and keep the roots cool.

Joe Pye weed is fairly hardy both to cold and to heat within the climates of its growing zones. Frost will cause the plant to begin dying back to the ground for the winter. Humidity (or lack thereof) typically isn’t an issue, as long as the soil remains moist.

Joe Pye weed is not easy to grow from seeds, because the seeds require a period of cold stratification in order to germinate. Purchased seeds or those saved from a spent flower head can be stored in the refrigerator for at least a month before planting. If starting indoors, start the seeds about eight weeks before the expected last frost. Or, they can be planted outdoors in spring.

Powdery White Residue Covers the Leaves

The Eutrochium genus has several species that are all known collectively Joe Pye weed, and several are cultivated as garden plants, especially Eutrochium purpuream ("purple Joe Pye weed" or "sweet Joe Pye weed"), and Eutrochium maculatum (spotted Joe Pye weed). Eutrochium purpureum is a late-blooming wildflower that’s native to eastern and central North America. It generally grows in upright clumps that reach up to 7 feet. E. maculatum has a natie range that extends further west to the Great Plains, with flowers that are somewhat more purplish. These species are very similar, however, and are often confused with one another.

Powdery mildew sometimes responds to fungicide sprays or powders, but you can reduce its appearance by avoiding overhead watering and giving the plants plenty of space for air circulation. Better yet, choose one of the named cultivars, which are generally bred for their resistance to mildew:

Though not nearly as common as powdery mildew, rust fungus can also leave brownish-orange spots on the leaves of Joe Pye weed. It's rarely a serious problem, but if the disfigurement bothers you, try treating the plant with a spray fungicide.

Temperature and Humidity

The various species of Joe Pye Weed are extremely similar in appearance, and the ones offered at local garden centers often are simply sold as "Joe Pye Weed" (Eutrochium) without any further species distinction. But serious gardeners might be interested in the species details:

Like many native wildflowers, Joe Pye weed is renowned for its easy-care attitude. Problems are rare and usually easy to solve:

In their native environment, these plants can be found in thickets and woodlands throughout the eastern half of North America. The plants are hardy from USDA Zones 4 through 9. They reach heights of anywhere between 3 and 12 feet (1-4 m.), offering great focal interest when using Joe-pye weeds in the garden. In addition, the flowers have a light vanilla fragrance that becomes more intense when crushed.

Plants die back to the ground in late fall. This dead growth can be cut back or left over winter and cut in spring.

What are Joe-Pye Weed Flowers?

Spring or fall is the most suitable time for when to plant Joe-pye weed. Due to the large size of Joe-pye weed, it makes a great background plant but also needs plenty of room to grow. In fact, they are best planted on 24 inch (61 cm.) centers as they will eventually form large clumps. When growing Joe-pye weed in the garden, group it with similar woodland plants and ornamental grasses.

Older plants can be divided and replanted in the early spring as new growth starts or fall. When the center dies out of Joe-pye weeds in the garden, then it’s time for division. You need to dig up the entire clump, cutting away and discarding the dead center material. You can then replant the divided clumps.

Gardeners value growing Joe Pye Weed for their big, mounding flower heads that are typically white, shades of pink and occasionally violet-purple. The flowers are loaded with nectar and pollen that attract native bees, honeybees and butterflies. In the fall, many species set copious seeds that are both ornamental as well as useful for attracting and feeding small seed-eating songbirds. The plants are highly resistant to browsing deer and rabbits.
