Pycnanthemum loomisii is a little known native mountain mint that hails from Illinois south to Florida. Our offering is from an Aaron Floden accession in Campbell Co., Tennessee. For us, Pycnanthemum loomisii has formed a 4.5' tall x 4.5' wide patch of sturdy stalks of peppermint-scented, grey-green foliage in 3 years. Compared to many of the highly invasive, running mountain mints, Pycnanthemum loomisii plays well with others...as long as you give it enough room. Loomis' mountain mint tops out at 4.5' tall for us in late June, when the upper leaves turn bright silver and are adorned with the tiny pink-lavender terminal flowers. The number of cool insects that it attracts to the garden is truly amazing!
