CT gardener and plantsman Chris Wojtas shared this curious, perennial Isodon sp. Chris thinks possibly Isodon nervosus, and originated from a nursery in Hubei. More research is required. Thousands of of bicolor blue and white flowers with dark burgundy calyces in mid autumn. Fragrant, mint-anise foliage gives way to golden canes through fall. Z6 at least, to 9’+, quart pots.
