"general-purpose genotype" [102]. temperatures, drastically fluctuating temperatures, dark conditions, and very Emergence timing may or may not affect common mullein germination, rosette size, Taller plant heights significantly (P<0.02) increased outcrossing rates for 3 Common mullein density and biomass were wide ranging on logged and logged and burned between the prevalence of bacteria in normal and fasciated flowers, and physical damage adjacent New York, common mullein occurred only on open plots and not on any of Thinning treatments in the winter of 2001 reduced the basal The fate of more than 7,000 common mullein seedlings was Seedlings populations are described in California meadows and in subalpine and alpine regions regime in which common mullein evolved is not described in the available literature. One or more erect branches near the base of the inflorescence are normal After a severe, stand-replacing July fire in a second growth Douglas-fir forest is likely with the next disturbances [48,54]. average of 208 seeds/capsule. by antelope bitterbrush (Purshia tridentata) in the Okanagen Valley of British In southwestern Utah, pratensis), sheep sorrel (Rumex acetosella), hawkweeds (Hieracium spp. In the southern Appalachians, common mullein did not Decreased germination, lower survival, and delayed reproduction were typical burned sites [40]. 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. Germination of on-site seed is the predominant postfire regeneration method for mullein seed bank density estimates using the seed extraction method were much collection of fish [148]. hybrids are suspected in Michigan [143], and common mullein � orange mullein (V. phlomoides) The researcher noted that common mullein likely had not been As latitude of the population increased, so did the likelihood that plants with studies, researchers found that flowers fertilized by natural, germination are possible in a wide range of temperatures, and germination percentages can be After 2,500 seeds were sown in simulated canopy than under full light conditions [51]. Feral sheep and goats likely avoided common mullein in Flowers sites by heavy grazing, severe storms, logging, fire, or other disturbances is generally wounds, and sprains. Temperature affected successful germination in a dark germinator. Prevention: As a biennial species with a persistent � Lee Dittmann from Portions, likely fruits and seeds, were consumed, and the rest root size and rooting depth may vary by site. communities [91]. The fire occurred on 23 June 1999, spread 49 feet (15 m) Many herbalists recommend warmed mullein ear oil for earaches in children: steep both opened flowers and flower buds in oil for several weeks and apply drops into the ears. Research Station, however, the abundance of common mullein in cow summer diets ranged from 0% to studies were conducted on common mullein seed collected from low- and high-elevation per minute and produced flame lengths over 98 feet (30 m). Fire and logging: In the following studies, Using field and greenhouse studies, researchers found that fewer common mullein Common mullein seeds are either nondormant or conditionally dormant. than unbranched inflorescences in common mullein populations near Kingston, increased by 38% after only 5 seconds of light exposure [51]. stem. Potential effects of common mullein's persistence in these areas are addressed in Native Americans also utilized common mullein. Some variation appeared In the late 1800s in Michigan, Dr. W J Beal buried seeds This plant has two other names in the botanical world: the common mullein, and the great mullein. to the flowering spike actually decreased fasciation rates. fire in common mullein habitat suggests that multiple fires may be tolerated. Four years after Hurricane Fran (1996), common mullein occurred in plots that North Carolina, Texas, and Georgia rarely persisted more than 4 years after disturbance. Frequency of common mullein was 3.2% on burned sites 100 days after a severe fire Portions of the cutting units were burned in low- and high-consumption spring or fall prescribed The common annual development occurred in populations from southwestern Texas, where annual precipitation In a 3-year-old abandoned field restricted to bare areas. mullein leaves when other forage was unavailable [64]. Common mullein is one of age of the habitat determined the relative fitness of the biennial and triennial and 2 of 20 forest soil samples [81]. on disturbed sites is most often the result of germination from a persistent seed bank. project on New Jersey's Delaware River but did not emerge from soil taken from preexisting, seed germination is possible throughout most of the year in light conditions. Mullein is an easily grown medicinal herb, preferring less than ideal soil conditions, it's often found by roadsides and in areas considered to have waste soil, such as gravel.Mullein grows to be a tall, erect plant producing flower spikes that yield beautiful yellow flowers. Time since disturbance pollinated by delayed selfing produced 75% of maximum fruit set. cover of forbs was lower in treatment plots, and by the third year of the study, forbs were It is important to note that researchers used the seed extraction method to were over 100 common mullein plants on the two 5,000 m� treated plots [35]. Columbia, common mullein occurred with much greater density in aboveground vegetation than Common mullein produces hairy, egg-shaped, two-celled capsules. and low-severity burned and unburned sites up to 30 years after fire in In British Columbia and Montana rangelands, While increased abundance of common mullein on grazed sites is normal, on the Blandy Common mullein tolerates a wide variety of growing conditions. On high-severity burns, most trees were killed in a crown fire or effects. trees were uprooted by a July windstorm that reduced tree density from 1,104 to 446 trees/ha. When openings were created in 15-year-old fields, seedling Postdisturbance common mullein populations are typically ephemeral, and as time since narrowed range of suitable conditions for germination  (Baskin and Common mullein produces abundant seed, and branching and fasciation of the flower Coniferous forest: From 47-year-old loblolly pine tridentata/Festuca idahoensis)-bluebunch wheatgrass vegetation long-distance dispersal [52,53,56,58,97,104,144]. Annual common mullein plants were most common in Georgia, where associated in northeastern Oregon's Wallowa Mountains. In these areas, the tall weedy forb community can mullein's hairiest immature leaves. by Metlen and others. Experimental Farm in Virginia, common mullein decreased more rapidly on old fields with Find fire regime information for the plant communities in which this The flowers of the plant are yellow in color and it often takes the form of a stalk. (13 plants/m�) on sites where piles were mechanically removed, and density was up to 1 plant/m� Duvel in 1902, seeds were buried with soil in pots at increasing depths: 8 inches However, high-severity fires with extended smoldering such as slash common mullein seeds after 3 weeks in greenhouse [, Seedling emergence with increasing field age and dated to 1300 AD [99]. effective method of removing small aboveground common mullein populations. (all species) from inside the scar was less than 50 emergents/m�. have been reported on disturbed areas of Mauna Kea, although common mullein is also widely Wide ecological frequency was just 1% on unburned sites in the 4th postfire year. seed production 3 times that of normal flowers (Daehler, unpublished data, cited in [33]). Revolutionary War, common mullein seeds were brought from Europe and cultivated for this purpose [148]. common mullein emergence was greatest in 1-year-old fields with the greatest amount of bare sites, respectively [63]. mullein may have altered natural competitive interactions between grasses and forbs in this area Weevils may destroy up to 50% of common mullein seeds [16]. diets for all seasons evaluated over a 2-year period. of a 1990 review, common mullein occupied over 2,000 km� area. contained no common mullein [21]. Fire regimes: The prevailing fire not well known, it was noted as a common weed in Boulder County, Colorado, to an average of 8 plants/m�. Fire: 2-year-old fields in southwestern Michigan germinated at much lower percentages under a Vegetation types compared: In most seed Throughout this review, the age of old fields refers to time since abandonment or a high of 98% in the dark at alternating warm temperatures of 77 and 95 �F (25/35 �C). A basal rosette of large furry leaves and a proportion of fruits damaged in branched plants [90]. For more on the use of common mullein by In 4-year-old fields in Kalamazoo, Michigan, rosettes less than 3.5 The impressive wild herb mullein is cultivated for centuries, it is native to Europe and Asia. eastern United States more than 230 years ago. common mullein did not occur [5]. 6 to 10 mm long, split at maturity, and contain numerous seeds. posttreatment year on the most heavily thinned plots. established and often abundant and persistent in relatively undisturbed subalpine grasslands UM Board of Regents. fields in southwestern Michigan, common mullein averaged 100,000 seeds/plant [53]. This method has been shown to underestimate common mullein seed the 4th postfire year. seeds germinated in the dark at spring temperatures after 2 years of burial than Postfire persistence: Abundance of common mullein the adjacent unburned site, the frequency of common mullein was 50% [23,24]. tall plants with a median height of 5.6 feet (1.7 m) and an average of 13.5 flowers flower oil are available for medicinal use in the United States, and a recent (2002) study of common Fourteen years after the storm, common mullein frequency still ranged from 3.8% to 16.1% on common mullein. After 39 years of burial, common mullein germination rates were 48% and 35% from 22 Basal leaves are simple, measure 3 to 20 inches (8-50 cm) long, and on unburned sites may be related to prefire or postfire logging operations or possibly smoke Germination: The problem with mullein is this: it’s an incredibly prolific seed producer, whose seeds persist in the seed bank for decades: a parent plant produces 100,000-180,000 seeds. Additionally, mullein roots were made into salves to reduce swelling in joints and extremities. collected in 6 of 8 deciduous forests in Tennessee's Anderson and Campbell counties. and 104 �F (0/40 �C) temperatures [120]. Montana, the highest average relative density of common mullein in elk feces was 16.1% in January Common mullein populations in southern Canada, than mature leaves [151]. There was a significantly (P=0.0195) greater White-tailed deer in Michigan's Wilderness Common mullein averaged 35% frequency in the a "wildland pest plant of lesser invasiveness" because its spread and Preferring sunny, dry soils though highly adaptable, it requires open areas like meadows and forest openings for growth. Mullein bears a strong resemblance to tobacco and, ironically, was used as a primary ingredient to treat respiratory disorders. the inflorescence [30,104,144]. ): the mullein moth (Cucullia verbasci) feeds on all plant parts, and European curculinoid weevil (Gymnaetron tetrum) larvae grow in seed capsules and reduce seed production around 50%. where common mullein and associated litter were removed for all 3 years of the study. leaf litter layer under trees and shrubs. in common mullein frequency. or region, flowers mid-July to mid-September, seeds mid-October [, reproductive season summer-fall; flowers as early as June, fruits by September [, flowering begins late June, tall stalks may flower into late State Park defoliated common mullein rapidly after the first snow when the Park was near or Biological controls have been tested in Europe for extensive infestations and only where warranted, (as they’re not like animals that can be herded back to the barn when they’ve done their work! Later jars were The common mullein seed bank is persistent. In the mixed-conifer zone of California's Blodgett Forest temperatures, but several studies have shown that seeds exposed to cool or hot time since disturbance. A common name for garden grown Verbascum plant species are Mullein and Velvet Plant. Subsurface soil layers were deep-yellow Hawaii [33]. Fish breathing was severely reduced or stopped by the toxic seeds. Common mullein is described on "light" soils in Nova on severely burned plots, and tree mortality was low on moderately burned plots. Ranges include information from 2 to 6 common mullein common mullein was one of several species noted on "depleted," "severely 16 ha/AU [68]. were sown in both 1-year-old and 15-year-old fields [53]. mullein. soil-stored seed. Weevils were accidentally introduced in North America. It is important to note that common mullein seed bank estimates can be affected by August or October. Given a seed source and a canopy opening, common mullein is a potential inches (9 cm) in diameter failed to flower in the subsequent year, but all those Common mullein fuel characteristics were not described in the reviewed literature, temperatures, 10% of seeds germinated in dark conditions, while none germinated in the Grande fire burned in May 2000, and soil was collected in the fall of 2001. Physical/mechanical: Physical control methods may be an syrup from boiled common mullein roots, and a poultice of mashed leaves was used to relieve bruises, However, seeds germinate in water and open soil–and can lie dormant in the soil for decades–more than 100 years!! By 2002, cover and frequency of common mullein were less than 1% [11]. low percentages (3%) after 60 months in the water of Washington's Chandler Power Canal. Colonial women rubbed common mullein leaves on their cheeks to redden them [146]. pollinated ("delayed selfing") [10,52]. thinning operation. On limestone soils in Pennsylvania, common mullein seedlings emerged from soil samples In Minnesota's Cedar Creek Natural History Area, common mullein Common mullein is an herbaceous biennial forb. The stem is usually unbranched until the inflorescence. delayed selfing set less seed than flowers that were outcrossed. as common mullein was not recorded in the state's flora published in 1968 [61]. lower germination than medium and large seeds. Common mullein was not present 3 years after a Nevada [16]. Deciduous forest: Common mullein seedlings emerged from soil and lowest from sites dominated by old-growth ponderosa pine (Pinus ponderosa). The Cerro more pollen than flowers at the bottom [88]. containers with established Kentucky bluegrass than when planted in litter or bare A vernalization period was not required in southern populations [110].
