Does best in moist (even very moist), slightly acidic soils, but can take average soils as well. Avoid high pH sites.


Winterberry holly blooms on old wood. However, pruning female varieties after blooming will remove any developing fruit, so pruning is not recommended except to remove entire branches in an effort to attain a specific form. Male varieties could be pruned after blooming, however, given the typically slow growth rate of winterberry hollies, pruning is not recommended for them either.


Mass plantings; hedges; cutting gardens; wildlife gardens; natural areas.

Growing Tips

One male plant will pollinate up to five females. Plant within about 50'/15.25m of one another to ensure pollination and good fruit set. Quite tolerant of shaded conditions; however, fruit set is best with at least 4 hours of sun each day.
