Plant Profile: Ilex 'Mary Nell'

This relatively recent introduction from the renowned Tom Dodd Nursery in Alabama showcases a stunning hybrid with three parent species: I. cornuta, known for its remarkable resilience and heat tolerance as the Chinese Holly; I. pernyi, or Perny Holly, which is favored for its attractive, compact foliage; and I. latifolia, commonly referred to as Lusterleaf Holly, distinguished by its broad, striking blue-green leaves. 'Mary Nell' has successfully inherited the best traits from these three varieties, demonstrating exceptional adaptability to southeastern landscapes, large glossy dark blue-green leaves, a dense pyramidal to columnar form, and an impressive ability to produce abundant bright red berries. In fact, 'Mary Nell' may surpass 'Nellie Stevens' as a premier choice for evergreen hollies in southeastern gardens.

This blend of characteristics results in a plant that combines the eye-catching foliage of I. latifolia with the refined growth habit of I. pernyi, alongside the robust landscape performance of I. cornuta and the prolific fruiting of a vigorous hybrid—making it a formidable contender among hollies. 'Mary Nell' can ultimately grow to heights of 20 to 25 feet, maintaining a moderately formal pyramidal shape and dense foliage. While it thrives in partial shade, optimal foliage quality and fruit production are achieved in full sunlight. This variety is adaptable to a wide range of soil types, making it suitable for even the most challenging gardening conditions. It is hardy across the coastal and Piedmont regions of the southeast, although it may struggle in harsh mountain winters. Like many evergreen hollies, 'Mary Nell' can be easily propagated through hardwood or semi-hardwood cuttings rooted in mist.
