Ilex x Koehneana 'Wirt L. Winn'
Wirt L. Winn is a very interesting variety of Koehne Holly. A medium
to large growing holly with dark green, heavily serrated leaves. New
growth is tinged burgundy / purple. Makes an excellent landscape
specimen due to its nice size, and beautiful foliage. Natural growth habit is strongly pyramidal, and requires little to no help to maintain such a shape. Wirt L. Winn bears
very large, handsome fruits in abundance - good berry producer.
Moderate to fast growth - can handle full sun to part shade. Very nice,
yet seldom seen holly. You just don't find these babies for sale very
We usually only have a very small number of this Holly variety available each year - not much material to propagate from, and increased difficulty to propagate from cuttings really limits our ability to have large numbers of these trees available. When we do have them available, we highly suggest trying them out. Truly a beautiful Holly tree when mature.

--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.
