Description

Strongbox® inkberry holly (Ilex glabra) is yet another innovative boxwood alternative from Proven Winners ColorChoice Shrubs. Like its sister plant Gem Box® inkberry holly, it’s a native evergreen with a neat, dense habit that looks like boxwood but is more durable and disease resistant. Strongbox® is more squat and “tuna can”-shaped than Gem Box, which is more of a globe. It needs no trimming to maintain this tidy shape and lends the perfect semi-formal accent to any kind of landscape. Especially nice in native plant and pollinator gardens! Plant inkberry holly as a low hedge, specimen, or use it as an edging. Though it is not quite as shade tolerant and deer resistant as boxwood, it’s more adaptable and of course, more disease resistant. History buffs, take note: this plants is called “inkberry holly” because Civil War soldiers used its berries to make a crude ink to write letters home. Note about berries: Strongbox inkberry holly is a female variety and can potentially develop berries when paired with Strong Box Inkberry Holly.

How to Grow

Soil: Moist but well-drained soils are best. Though inkberry 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: Trim as needed to maintain shape and size desired. Save major pruning for mid-late spring, after new growth has emerged but before it becomes hard and woody.
 

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.

Grow with confidence

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:

Not sure just how many plants will fit in your garden? Our calculator gives you the exact amount of plants required for your space. Simply update the values and the calculator will re-calculate accordingly. Spacing information can be found in the 'How to Grow' tab on each plant's page.
