It looks good and does as well as the red cultivars. A branch sport that came from a Winter Red plant discovered in 1984 at Simpson Nursery in Vincennes, Indiana. Cold Hardy to USDA Zone 4. |

Winter is long here in zone 5 and can be very boring, I've been pairing these up with Viburnum dilatatum 'Asian Beauty' and Calicarpus. The combination of berries looks great and adds some cheer and interest as the garden fades. I highly recommend this shrub and some of it's companions if you are looking for some fall/winter interest in your landscape! |
