BUGLEWEED 
Lycopus virginicus, L. 
Other English names: Water Horehound, Ditch Horehound, Vir- 
‘ginia Horehound, Buglewort, Paul’s Betony. 
Native. Perennial. Propagates by seeds and by stolons. 
Time of bloom: July to September. 
Seed-time: August to November. 
Range: Labrador to British Columbia, 
southward to Florida, Alabama, and 
Missouri. 
Habitat: Wet meadows, banks of streams; 
often clogs ditches. 
A common weed, of which the most 
troublesome part is the long, thread-like, 
leafy, interlacing runners, reaching out in 
all directions from the parent, sending up 
new plants and making tangled mats. The 
plant is used in medicine and brings three 
or four cents a pound in the drug market. 
It would be some satisfaction, in clearing out 
a ditch, to make the weed itself pay for the 
labor. For this purpose the herb must be 
pulled entire while in full flower, and dried 
in the shade. 
Stems six inches to two feet high, slender, 
obtusely four-sided, usually somewhat hairy. 
Leaves dark green or tinged with purple,
