Ilex crenata 'Sky Pencil'

Overall Description

Sky Pencil Holly was first introduced back in 1985 by the U.S. National Arboretum, and has increased in popularity in the landscape industry with each passing year. This Holly cultivar is not known for berries, and does not have the type of foliage one would normally associate with the word "holly" - there are no prickly, pointy, needles or spines to the foliage of Sky Pencil at all. In fact, the foliage is rather small, oval shaped........somewhat similar to that of Boxwood, but with more of a glossy finish to it.

The growth habit of Sky Pencil Holly is what really sets this Holly cultivar apart from all the others. It is naturally a very tall, slender, narrow grower - reaching heights of 8 - 10 feet on average, but with an overall average width of only 2 - 2 1/2 feet. And there is no trimming / pruning required to keep them within these height & width parameters. So, when you combine the wonderful features offered by Sky Pencil Holly, you get the following: nice green glossy evergreen foliage year round, tidy slender columnar growth habit, mature height range of 8 - 10 feet on avg, even tolerates semi shaded locations.....although growth rate will slow just a bit with increased shade. Responds very well to trimming / pruning if height is needed to be kept at a shorter height than if allowed to grow naturally.

Makes a great choice for a low maintenance privacy screen or border in areas where width is restricted, or limited. Has a great formal look, which lends itself well to use along walkways, driveways, and on sides of entrances. Works very well when planted at corners of buildings....especially if you need to hide an unsightly rain gutter downspout - have also seen them used to plant around central A/C units to help hide them from view.

--Fertilization / Feeding :
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
