USDA Plant Hardiness Zones: 6a-9b  Find Your Zone

Special Attributes

At the top of our list of tall hollies, the 'Wirt L. Winn' is a care-free holly with large, lustrous, rich-green evergreen leaves on a broad, strong pyramidal form. New leaves emerge a reddish-purple for extra appeal. 'Wirt L.Winn' produces LOADS of LARGE green berries in summer that turn bright red in fall and persist throughout winter. Can be grown as a large shrub or tree with a natural, pyramidal form that beautiful enough to be a specimen tree while growing fast enough to form a tall privacy screen. Tolerates moderate shade very well and more cold hardy than other cultivars. We are truly proud to offer this amazing, hard to find holly.




Landscape & Garden Uses

Growing naturally in a pyramidal form to 20 feet or more tall and 10-12 feet wide at its base, the Wirt L. Winn Holly can be grown as a large shrub or small tree. As a large shrub it's ideal for use in staggered or single rows as a tall privacy screen, as a street tree, or to frame the corners of tall homes or other structures. As the plant grows, lower branches can be removed to desired height to form a magnificent focal point specimen for use in landscape borders or home foundation plantings. Also nice grouped in landscape borders. A fine addition to bird gardens and holly gardens. 

Spacing Recommendations:  6-8 feet apart for privacy screens; 14 feet or more apart for space between trees




Cultural Preferences

Wirt L. Winn Holly is exceptionally easy to grow. It adapts to many soils preferring a moist but well-drained acidic soil of average fertility and will grow in sun or shade. Alkaline soils result in chlorosis (yellowing of leaves) which can be corrected by the application of chelated iron and/or soil sulfur. More berries are produced in full to mostly sun however you can expect a good crop in  moderate shade. Low, to no maintenance when left to grow natural. That said, many landscapers will perform an annual pruning or shearing to maintain a more formal appearance or to control size.

Important Note:  Any heavy pruning after spring flowering will reduce or eliminate berry production.
