    Definitely has winter interest with its red berries that last well over three months in my zone 6b garden, from November through February. It is a great plant for the birds to feed on during winter. The white blooms are very small and nothing special in early summer. Mine are doing well on the north side of the house, where they get a lot of afternoon shade. I have 'Southern Gentleman' on the west side of the house as a pollinator for 'Winter Red'.

    'Winter Red' is the most used of the several Winterberry cultivars offered. It is a full-sized cultivar like the mother species, but its fruit is very bright red, a little larger, and profusely borne. Its leaves are relatively large, long and sharp. "Southern gentleman' is the male cultivar most commonly used to pollinate this female cultivar.
