COMMON MULLEIN - Scrophulariaceae - (Figwort family)

This biennial produces a large, thick rosette of fuzzy leaves the first year and a single, stout, erect stem, 2 to 6 feet tall, the second year. The leaves are alternate, overlapping one another, light green, densely wooly. Flowers are sessile, borne in long terminal spikes, sulfur yellow, 5-lobed and more than an inch in diameter. Fruits are 2-chambered with numerous, small, angular, brownish seeds, 1/32 inch long.

This weed was introduced from Europe, but it is a native of Asia and is common throughout the temperate parts of North America. It is a common sight along river bottoms, in pastures, meadows, fence rows and waste areas, especially on gravelly soils. Because of the large number of seeds produced by each plant, it is difficult to control. Livestock will not eat the plant because of its wooliness. Flowering and seed production occur from June to August.

Mullein is very competitive and likes disturbed soils along the road right of way or steep eroding hillsides. It is very herbicide resistant, responding best to Telar at 1 to 2 ounces per acre. It is likely that cutting off seed stalks and removing them, in conjunction with the herbicide treatment, would increase chances of eradication. In Fremont County there are just a few isolated sites where Mullein can be found, so an aggressive campaign would pay future dividends.
