It is a pretty, evergreen, low shrub to about 2.5 feet high and can get 8 feet wide or more in time. This cultivar grows more informally than most other cultivars into a spreading form, which is very nice. It is one of the more used cultivars available at many Mid-Atlantic nurseries. Not for shearing or formal landscaping. When I have to prune one of these lower Japanese Hollies it is usually only lightly, but older plants need deeper pruning and it hurts to reach deep into them, as they have hard spurs on some branches and just stiff, hard twigs. A male cultivar so it does not bear the black berries. Selected from Hoogendorn Nursery out of Rhode Island. I prefer the similar American native species of the Inkberry Holly, Ilex glabra, because it is soft and does not hurt.

I have the Japanese 'Hoogendorn' holly planted in several locations and love it for its natural looking and low spreading form (2 1/2 x 4 approx on plants that have been in the ground awhile.)

Multiple stems support a rounded mass of small broad boxwood-like leaves. Attractive little globular mounding shrub, supposedly can reach to 4', but tends to be compact, spreading wider rather than taller. Very suscepticle to Black Root Rot. Cultivar sometimes spelled 'Hoogendoorn'
