"Mexican Oregano: http://metalab.unc.edu/herbmed/culiher5.html#ch_2_29_4_mexican From: Chris McElrath <Mcmariah@AOL.COM> Mexican oregano is a general name for several plants, all of which have a strong oregano flavor: Poliomintha longiflora, Lippia graveolens, and Monarda fistulosa var. menthifolia. These are probably the most common but there are others. So, it comes down to: Mexican oregano is a common name which is used for several different species that grow in the southwestern US and Mexico. If you can find one, it probably has more flavor than the ubiquitous O. vulgare" -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- but THIS one is what i believe is most often sold packaged as Mexican Oregano in southern California. at ... http://rampages.onramp.net/~gardens/perenial.htm#polimintha lon. "Polimintha longiflora MEXICAN OREGANO 1-2 ft. Lavender flowers spring-fall. Deciduous (evergreen in warm winters). Most well drained alkaline soils. Sun to Part sun. This shrubby perennial covers itself with tubular-shaped lavender flowers all summer long, making it a good addition to a flower bed. The small leaves are extremely fragrant with the aroma of oregano (hence its name), and can be used to flavor meats or beans, so this is also a good plant for the herb garden. Its branches can be long and trailing, so it also looks good draped over a wall or rocks. It is very drought tolerant and must have good drainage to thrive" ....................................................................................................... this is a delicious addition to many Mexican foods, but it can be a bit overpowering in quantities equivalent to true oregano measurements. i love mexican oregano (Polimintha longiflora) in tacos. a little experimentation will get the flavor that you like! regards peter g
