Blooms are abundant and look delicate and clean come late spring when they burst on the scene. But don't be fooled by its elegant persona, Phlox 'Amazing Grace' is a tough little plant that will brighten your mountain rock garden, or gracefully adorn the urban embankment when planted in mass as a gorgeous groundcover.
