Plant Spacing

Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:

bush distance

Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

More Information

Description Could your landscape use a little pizzazz in winter? Berry Heavy® winterberry holly (Ilex verticillata) from Proven Winners is just the plant to do it! Unlike what you may think of with other hollies, this super-showy native species is deciduous – that means it loses its leaves in winter. But far from being a liability, this quirk gives its abundant set of big, bright red berries in fall and winter even more impact in the landscape. Winterberry holly blooms in late spring with small white flowers. These soon develop into green berries, which aren’t very noticeable since they’re hidden in the leaves. As the cooler temperatures of autumn come along, the berries turn red. In mid-autumn, the foliage blazes bright yellow, then drops to reveal the berry-laden branches. It is spectacular! Branches of mature plants can be cut and used in arrangements and for other holiday décor.

A note about winterberry holly pollination: Winterberry holly plants are either male or female, and both a male and female plant need to be present in order for fruit to form on the female. Berry Heavy is a female variety, so you will need to purchase the male variety, Mr. Poppins winterberry holly, as well. Only the female plants will develop berries, but one male will pollinate up to five females. Wondering how far apart you can plant the male and female holly plants? Anywhere within about 50’ of each other – the distance you can expect a pollinator to fly on a single foraging trip – is suitable. Details Botanical name: Ilex verticillata 'Spravy'
Common name: Winterberry holly
Zone: 3-9
Sun exposure: Full sun (6+ hours sun) to part-sun (4-6 hours sun)
Height x width: 6-8' tall and wide
Flower color: White flowers develop into green, then red, berries
Foliage color: Green
Season of Interest: Fall-winter
Bloom time: Spring
Features: Winter interest, rabbit resistant, Proven Winners, native, heat tolerant, fall color, deer resistant, cold tolerant, best for beginners
Uses: Hedge, native plant gardens, wildlife gardens, specimen (be sure to pair with a male plant).
 How To Grow Soil: Moist but well-drained soils are best. Though winterberry holly can take some dryness, foliage will begin to brown if it dries out frequently or severely.
Light: Full sun (6+ hrs/day) to part sun (4-6 hrs/day).
Water: Average to abundant (as long as soil is well-drained).
Space: 2-3' apart, depending on landscape role.
Fertilizing: If desired, fertilize in early spring, once the ground has thawed, with a granular rose fertilizer. A second application may be made in late spring/early summer as well.
Winterizing: 2-3" of shredded bark mulch is important to protect the shallow roots and minimize water loss. Do not allow plants to enter winter "thirsty"; dry soil during cold, windy weather is the main cause of leaf browning or even the plant dying.
Maintenance: Female winterberry hollies cannot be pruned any time of the year without impacting flowering and thereby, fruiting, so it's best to avoid pruning them altogether except to remove any dead wood and once mature, to remove one or two of the oldest stems each year to encourage new and vigorous growth..

Garden Care

Our Guide for Fall Planting

The start of fall may signal the gardening season is coming to a close, but it’s not over yet! There is still plenty of time to enjoy colorful flowers and foliage or even sprinkle in some new perennials and shrubs before winter arrives.
