Upright plant with mid-green leaves in pairs up its stalks. The leaves near the top of the stalk are much paler, almost white right at the top where the flower cluster sits. When you get up close, you can see the individual purple-and-white flowers in the cluster. From standing height, they look like creamy white pompoms. The flowers don't open all at the same time, so the flowerhead keeps a bit of a messy appearance, with unopened and spent flowers alongside the ones showing their speckled petals. Like all mountain mints, this plant's foliage is strongly scented; to my nose, it's not particularly minty, but a fragrance all its own.
Native to the Eastern US.

| The ghostly coloration of the dark leaves comes out more strongly in some plants and settings; this photo of a second-year plant was taken in July |

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston. About my plant portraits
