What an inspired combination!
A mix of shrubs (yes, you’ll have to remove them eventually and plant in the ground) along with a ground cover wintergreen and sparkling white hellebores, this combo will look great right through the winter in zones 7 – 9. Colder zones will need to substitute something a bit more hardy for nandina (we suggest a holly such as Nordic™ Inkberry Holly, which looks somewhat the same and stays somewhat small).
Who needs lots of flowers, right?
