Bushy St. John'S Wort
hypericum densiflorum
The Bushy St. John's Wort (Hypericum densiflorum) is a delightful, deciduous woody shrub native to the damp soils of the eastern United States. Celebrated for its lush, rounded habit and remarkably dense clusters of star-like yellow flowers, this plant lights up wet meadows and bogs from mid-summer into early autumn. It serves as a vital resource for local pollinators, who are drawn to the sheer abundance of its pollen-rich stamens. Gardeners and restoration ecologists value this resilient shrub for its ability to thrive in poor, waterlogged, and highly acidic soils where other plants struggle. Its tolerance to flooding and attractive form make it an excellent choice for rain gardens, bioswales, and wetland restoration projects, helping to stabilize banks and filter runoff while adding a vibrant splash of color to the landscape.
Lebensraum: Found in damp, acidic soils of wet meadows, bogs, pine flatwoods, and along riparian borders.
Aussehen
This densely branched, rounded shrub typically grows between 50 to 200 centimeters in height. It features narrow, linear to oblong green leaves arranged oppositely along the stems, which turn a warm yellow-brown in the autumn. Older branches exhibit a characteristic peeling, papery bark with a reddish-brown to grayish hue. During its peak bloom, the shrub is covered in tight, flat-topped clusters of small, bright yellow flowers, each measuring about 1 to 1.5 centimeters across. These flowers are distinguished by five distinct petals and an exceptionally bushy center of numerous protruding stamens, giving the entire inflorescence a fuzzy, golden appearance.

Interessante Fakten
Like other St. John's Worts, its leaves contain tiny, translucent glands that resemble pinpricks when held up to a light source.
The bushy, fuzzy appearance of the flowers is due to the dozens of long stamens that erupt from the center of each tiny blossom.
The species name 'densiflorum' literally translates to 'densely flowered' in Latin, perfectly describing its packed clusters of golden blossoms.
