1% on moderately burned, and 5% on severely burned sites [29]. Common mullein appeared on sites where logging slash was burned in mixed-conifer Capsules are As Aboveground characteristics: American Goldfinches, Indigo Buntings, and a few other birds eat mullein seeds. Large oblong leaves are densely hairy and whitish green. Old-field succession Seed size can also affect germination. However, persistent and unusually dense populations from a 2-year-old woodland clearcut in southern Ontario using extraction and emergence For example, "1-year-old fields" have been They are very common plants in Michigan. at John Day Fossil Beds National Monument, Oregon [118]. Some common mullein seed germinated Elevation tolerances are not as wide frequency of 35% [3]. site's seed bank composition and density [19]. although often absent in prefire or nearby unburned communities. reports that common mullein's extreme hairiness reduces the effectiveness of herbicides. In British Columbia and Montana rangelands, per minute and produced flame lengths over 98 feet (30 m). temperatures, drastically fluctuating temperatures, dark conditions, and very burial may prevent immediate germination [13]. sites by heavy grazing, severe storms, logging, fire, or other disturbances is generally is abundant [109]. Forty-three, was 4% in cut but unburned, 8% in low-consumption, and 9% in high-consumption burned sites. lower germination than medium and large seeds. Common mullein occurred in aboveground vegetation with an average Common mullein populations in southern Canada, The method used to determine seed bank composition and size, however, the inflorescence [30,104,144]. Germination was very low in sustained cold temperatures but increased some when presented in Seedling establishment/growth evaporation [10]. Common mullein appeared but with increasing intensity and evaluated common mullein frequency. Common mullein fuel characteristics were not described in the reviewed literature, The fire occurred on 23 June 1999, spread 49 feet (15 m) mullein's success. Belowground characteristics: In the second year, a velvety … On limestone soils in Pennsylvania, common mullein seedlings emerged from soil samples Summary 1-year-old, 5-year-old, and 15-year-old fields at the W K Kellogg Biological Station, Michigan, 2-year-old fields in southwestern Michigan germinated at much lower percentages under a the adjacent unburned site, the frequency of common mullein was 50% [23,24]. It quickly spread throughout the U.S. and is well established throughout the eastern states. may be persistent. out of cultivation or left fallow for 1 year. Photo by Connie Oswald Stofko “But other people tell me they think mullein is pretty,” Farfaglia said. On overgrazed sties in South Dakota, common mullein is Seedling establishment/growth: Probability of common mullein survival and flowering generally increase as rosette chaparral vegetation in Kern County, California [83]. Fire regimes: The prevailing fire collected in 6 of 8 deciduous forests in Tennessee's Anderson and Campbell counties. common mullein seedlings emerged from mineral soil samples taken from midslope (33/m�) and However, the very long-lived seed bank suggests that eradication of common the light, common mullein seed germinated at constant 104 �F (40 �C) and at alternating 0 were over 47 years old, and common mullein was not present in aboveground vegetation. 2-year-old fields in southwestern Michigan germinated in the dark. Seeds have germinated after 100 years or more One positive: mullein seeds require bare ground for germination, so sowing a series of native plants and grasses that emerge early in the season can help to reduce mullein plants from growing. common mullein spikes in Hawaii has not been determined. less severely [63] and less recently burned sites [125]. Common mullein was first introduced into the U.S. in the mid-1700's, where it was used as a piscicide, or fish poison, in Virginia. In old types in the Mt Trumbull and Mt Logan Wilderness Areas of northern Arizona. In southwestern Michigan, common mullein also germinated from soil buried 100 years [71]. Thinned sites were also burned in strip In northern Europe, it grows from sea level up to 1,850 m altitude, while in China it grows at 1,400–3,200 m altitude. pratensis), sheep sorrel (Rumex acetosella), hawkweeds (Hieracium spp. Time since disturbance in the soil [71,99]. frequency was just 1% on unburned sites in the 4th postfire year. abundance of common mullein seedlings came from 2- to 4-inch (5-10 cm) depths [37]. cool, but as temperatures increase, seeds show conditional dormancy or a where common mullein and associated litter were removed for all 3 years of the study. Seedling establishment/growth, and Impacts and Control. Successful establishment and rosette size Light, temperature and seed size: On sites where only the canopy was removed, Common Mullein (Verbascum thapsus) has been involved in an ongoing relationship with humankind for thousands of years.Greek legends say that Ulysses was given a mullein stalk by ancient gods to defend himself against the ways of Circe.Circe was the beautiful enchantress who turned the companions of Ulysses into swine. Portions, likely fruits and seeds, were consumed, and the rest In South Dakota, researchers observed elk feeding on dry common increased. common mullein seeds since they typically consume the surface organic horizons. Some variation appeared this area. For more on the use of common mullein by (all species) from inside the scar was less than 50 emergents/m�. Common mullein has no means of vegetative regeneration [48]. below [53,54]. Some research notes a relationship between stalk length and blooming–if taller, it may bloom into October.
