Winterberry - Berry Heavy®

Ilex verticillata 'Spravy'

Berry Heavy® is a deciduous holly which produces a very heavy, bright red berry crop. The spectacular fall and winter show is sure to brighten the short days of the season. Winterberry holly is a dioecious shrub, which means that each plant produces either male or female flowers. Berry Heavy® is a female plant which requires the male pollinator, Mr. Poppins®. One male plant will pollinate up to five females. Plant Berry Heavy® within about 50' of Mr. Poppins® to ensure pollination and good fruit set. Keep in mind, the male plant does not produce berries. Fruit is not edible. Suitable in mass plantings, hedges, cutting gardens, wildlife gardens and natural areas. Attracts pollinators. Deer resistant.

PLEASE NOTE: To produce berries, you'll need Mr. Poppins® Be advised, the fruits of Winterberry are poisonous to humans.

Our plants come with extra large and fibrous root systems, ready to plant and flourish!

    If I add soil acidifier regularly, do you think this would grow in NE Wisconsin (with our extreme limestone and therefore alkaline soil)?

    You should make sure to do a soil pH test first. 6-7 is considered neutral. The Winterberry would not like a high pH soil which is anything 7.5-8.5. So depending on what your test reveals you should amend accordingly to make your soil in the 7.5 or lower range. Typically you use sulfur to lower your pH to make it more acidic.

    How do I order a male and female set of plants?

    Apr 12, 2021, 01:34 PM

    You need to order at least one Mr. Poppins (male) for every (7) Berry Heavy (female) plants

    How many chill hours do they require? Thank you

    I would suggest an internet search but most Winterberries require 600 chill hours. This is a registered trademarked shrub, you cannot propagate it.

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.

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.
