352 LABI AT AE (MINT FAMILY) 



Time of bloom : April to July. 



Seed-time: Late May to August. 



Range: Newfoundland to Ontario and Minnesota, southward to 



Georgia and Kansas. 

 Habitat : Moist or shady soil ; lawns and yards, waste places. 



In old days, before the hop took its place, this plant was used 

 for flavoring and clarifying the home-brewed ale. Like the Plan- 

 tain, it seems almost domesticated and is a familiar weed about 

 dwellings and in towns. 



Stems slender, prostrate, and creeping, with many small, ascend- 

 ing branches, very leafy, three to five inches high. Leaves rounded 

 or kidney-shaped, scallop-toothed, green on both sides, with slender 

 petioles. Flowers in small axillary clusters, pale purple, spotted 

 with deeper purple; corolla about a half-inch long, its upper lip 

 with two lobes, three lobes in the lower lip, the upper pair of 

 stamens nearly twice the length of the lower ones, rising against 

 the upper lip ; the tube more than twice the length of the five- 

 lobed, hairy calyx. The four small nutlets ovoid and brown. 



Means of control 



It is almost impossible to dig out this weed and get all of the 

 slender, creeping rootstocks. If the infested ground is a lawn the 

 surest method is to skin off the rather shallow layer that contains 

 the roots and probably also a good supply of the seeds, and relay 

 with new sod or sow with clean seed.
