Ilex cren Patti O Box® Description
Patti O Box™ Japanese holly (Ilex crenata) is the perfect evergreen for a formal accent anywhere. This favorite Proven Winners evergreen naturally grows as a narrow pyramid of very deep green foliage. Tiny, concave leaves give it appealing texture. We especially love it as the centerpiece of a container or placed on either side of an entryway. Its strong shape makes it perfect for covering with string lights at the holidays or any time! You can also trim it into topiary spirals, poodles, anything you can imagine.
Japanese holly tolerates some shade. It needs moist but well-drained soil for best growth and in the colder areas of its hardiness range, should be protected from harsh winter winds.

Soil: Moist but well-drained soils are best. If broadleaf evergreens like Japanese holly dry out too much, their foliage will begin to brown.
Light: Full sun (6+ hrs/day) to part shade (4-6 hrs/day).
Water: Average to abundant (as long as soil is well-drained).
Space: 3-5' 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. If growing in a container with annuals that you'll be fertilizing regularly, you can skip the spring application.
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.
