Wild Golden Glow (Rudbeckia laciniata)
Wild Golden Glow, also known as Cutleaf or Green-headed Coneflower, is an herbaceous perennial herb in the Aster Family native to North America. It is found in most parts of the United States and Canada, usually close to water sources or moist soils. It grows 3–6 feet tall with grey-green, jaggedly-cut leaves, and blooms with bright yellow flowers. Its well-known cousin is the Black-eyed Susan (R. hirta) (“Rudbeckia laciniata,” 2019). R. laciniata is used in traditional Ojibwe (Chippewa) and Aniyvwiyai (Cherokee) medicine for gastrointestinal illnesses and as a treatment for burns. From Lee et al. (2012), “Extracts from the plants have been used as traditional Chinese medicine in the treatment of the common cold, and urinary diseases.” The young leaves are also used as a food source (Moerman, 2009). Current research on Wild Golden Glow focuses on its potential antifungal properties and as a source for antioxidants (Lawson et al., 2020; Lee, Cho, Han, Choi, & Lee, 2012; Lee, Shin, Choi, & Lee, 2014).
- Effect of Rudbeckia laciniata invasion on soil seed banks of different types of meadow communitiesby Elżbieta Jędrzejczak on June 29, 2022 at 10:00 am
In the last decades, biological invasions become the main driver of biodiversity loss. The changes can be noticed not only in the above-ground diversity but also in the underground, including seed banks of native vegetation. In this study, we focus on Rudbeckia laciniata, a species introduced to many European and Asian countries, to characterize its soil seed bank as well as to answer the question, how the species influenced soil seed banks of meadow plant communities in two types of habitats…
- Volatile Compositions and Antifungal Activities of Native American Medicinal Plants: Focus on the Asteraceaeby Sims K Lawson on January 23, 2020 at 11:00 am
In the past, Native Americans of North America had an abundant traditional herbal legacy for treating illnesses, disorders, and wounds. Unfortunately, much of the ethnopharmacological knowledge of North American Indians has been lost due to population destruction and displacement from their native lands by European-based settlers. However, there are some sources of Native American ethnobotany remaining. In this work, we have consulted the ethnobotanical literature for members of the Asteraceae…
- Comparative ozone responses of cutleaf coneflowers (Rudbeckia laciniata var. digitata, var. ampla) from Rocky Mountain and Great Smoky Mountains National Parks, USAby Howard S Neufeld on August 21, 2017 at 10:00 am
Cutleaf coneflower (Rudbeckia laciniata L. var. digitata) is native to Great Smoky Mountains National Park (GRSM) and an ozone bioindicator species. Variety ampla, whose ozone sensitivity is less well known, is native to Rocky Mountain National Park (ROMO). In the early 2000s, researchers found putative ozone symptoms on var. ampla and rhizomes were sent to Appalachian State University to verify that the symptoms were the result of ozone exposure. In 2011, potted plants were exposed to ambient…
- Few effects of invasive plants Reynoutria japonica, Rudbeckia laciniata and Solidago gigantea on soil physical and chemical propertiesby Anna M Stefanowicz on September 26, 2016 at 10:00 am
Biological invasions are an important problem of human-induced changes at a global scale. Invasive plants can modify soil nutrient pools and element cycling, creating feedbacks that potentially stabilize current or accelerate further invasion, and prevent re-establishment of native species. The aim of this study was to compare the effects of Reynoutria japonica, Rudbeckia laciniata and Solidago gigantea, invading non-forest areas located within or outside river valleys, on soil physical and…
- The growth and phosphorus acquisition of invasive plants Rudbeckia laciniata and Solidago gigantea are enhanced by arbuscular mycorrhizal fungiby Marta L Majewska on September 2, 2016 at 10:00 am
While a number of recent studies have revealed that arbuscular mycorrhizal fungi (AMF) can mediate invasive plant success, the influence of these symbionts on the most successful and high-impact invaders is largely unexplored. Two perennial herbs of this category of invasive plants, Rudbeckia laciniata and Solidago gigantea (Asteraceae), were thus tested in a pot experiment to determine whether AMF influence their growth, the concentration of phosphorus in biomass, and photosynthesis. The…
