More Information

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. However, there are no compatible males currently on the market to ensure the cross pollination required for fruit to form. Details Botanical name: Ilex glabra 'ILEXFARROWTRACEY'
Patent #: PP#30,147
Common name: Inkberry holly
Zone: 5-9
Sun exposure: Full sun (6+ hours sun) to part-sun (4-6 hours sun)
Height x width: 2-3' tall and wide
Flower color: White
Foliage color: Green
Season of Interest: Year-round
Bloom time: Spring
Features: Evergreens, native, deer resistant, Proven Winners, container plants, best for beginners
Uses: Hedge, low hedge, specimen, containers, formal gardens, native plant gardens
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.

Very Small

Heathy plants but quite small.

Thank you for your feedback. We’re sorry you’re not satisfied with your plants! On each product page and our plant sizes page, we note that all of our plants are young. The size of our plants varies depending on the time of year and whether they were recently trimmed. The most important thing when purchasing plants, online or in garden centers, is a full and robust root system, which we prioritize. Trimming only encourages stronger root development! All orders are covered by our 60-day guarantee, so please reach out to claims@greatgardenplants.com to start the claims process if necessary.

Excellent value for the price

In April I ordered a large number of ilex glabra Strongbox for a beautification project in a public NYC park. It is now mid-July and all of the shrubs look great and have shown new growth. I chose GGP because of the selection, ratings, and competitive pricing and I will most definitely order with them again.

Beautiful and well packaged!

Ordered the gallon size. Great size and condition with new growth started already. It's potted up in a nice container and has started blooming beautiful tiny flowers all over. Do not hesitate to order this plant or any plant from this wonderful company. Great packaging and tremendous customer service.
