This hebe's name is a bit deceptive, as 'Nana' implies a dwarf variety. Maturing to three feet tall and up to two feet wide, 'Purpurea Nana' is fairly average in size, not the smallest and certainly not the biggest. That said, the coloring of this evergreen shrub is anything but average, with erect, reddish-purple stems neatly lined with green to purple foliage. This hebe is also one of the hardier varieties, making it an attractive year-round addition to sunny spots in the garden. A light trim in late fall or early spring will keep this hebe compact and tidy, year after year.
