Gardeners' Notes:

This is the second most planted cultivar of Inkberry Holly in southeast Pennsylvania, after Shamrock. It has larger, thicker leaves and can have foliage close to the ground. It is a handsome native plant of the East Coast region and along the Gulf of Mexico. Does well in draining wet or moist soils that are at least a little bit acid. Doing well in my all clay soil of pH 6.9. Inkberry is soft to the touch and has flexible branching, unlike the similar Japanese or Box-leaved Holly that has very stiff branching and some sharp woody spurs on stems so that one can be poked.

Will grow in boggy/wet soil in full sun. Ours is planted beside our pond and the soil never dries out. Foliage leaves a lot to be desired, color is good but foliage is "thin" and the branches tend to get leggy looking, so pruning is a must. Deer love this shrub, so make sure and cover over winter if you have deer in the area. Ours has grown to about 3' tall and stays there. Not the nicest looking shrub we have and so I'm giving it a neutral rating.
