Yaupon (Ilex vomitoria 'Nana')
Ilex vomitoria 'Nana' is a dense, dwarf Yaupon holly ideal for hedges or screens, offering evergreen structure and drought tolerance in Zones 7-9.
Complete Plant Information
Overview
The dwarf cultivar Ilex vomitoria ‘Nana’, commonly known as Yaupon, provides excellent year-round structure for landscapes where space is limited. This dense, rounded broadleaf evergreen makes a superb substitute for larger hollies, retaining its deep green foliage throughout the year. It is highly valued for its adaptability, tolerating tough growing conditions including periodic dry spells once established.
This specific variety of Yaupon reaches a pleasing dwarf size, typically 3 to 5 feet tall and wide, making it exceptionally versatile for foundation plantings or low hedging. While it produces small, generally inconspicuous greenish-white flowers in April, female plants may yield small red drupes if a male pollinator is nearby. Its resilient nature and manageable size ensure Ilex vomitoria ‘Nana’ remains a popular architectural choice across the Southeast.

How to Grow
Planting Ilex vomitoria ‘Nana’ should ideally occur in spring or fall when temperatures are moderate, allowing the roots to establish before extreme heat or cold arrives. This dwarf Yaupon prefers average, well-draining soils, thriving in conditions ranging from medium moisture to quite wet—ideal for rain garden applications. Though adaptable, ensure it receives full sun to part shade; too much deep shade can thin out its desirable dense form.
Watering should be consistent, aiming for medium moisture, but established plants demonstrate impressive drought tolerance compared to many broader holly species. While maintenance is generally moderate, promptly remove any root suckers unless you are actively encouraging naturalization. Pruning, if necessary for shaping, should be performed in winter when the plant is dormant.
A crucial note for fruiting: The plants are dioecious, meaning separate male and female individuals exist. If you desire the fall color provided by fruit, ensure a male pollinator is situated nearby to service the female shrubs. Gardeners attempting to grow this evergreen in colder areas near Zone 7 boundaries should seek a protected microclimate and apply a generous winter mulch.
Landscape Uses
The compact, dense habit of Ilex vomitoria ‘Nana’ makes it an exceptional choice for formal or informal edging along walkways, offering dependable evergreen texture. Because it tolerates wet soil conditions, it excels when positioned as the primary structure in a rain garden, effectively managing runoff while looking sharp. It functions admirably as a low screen or a defined border hedge where taller specimens would overwhelm the space.
Beyond utility, this Yaupon cultivar lends itself well to topiary work for advanced gardeners seeking architectural focal points. Consider pairing the dark green foliage with contrasting textures, such as fine-leaved ornamental grasses or broad-leaved hostas in partial shade areas. The traditional use of the leaves to brew a stimulating beverage also adds a layer of historical intrigue to this hardy shrub.

Although the flowers of this dwarf Yaupon are insignificant to human eyes, they provide early season foraging opportunities when they bloom in April. The true wildlife value of the parent Ilex vomitoria species lies in its persistent red fruit, which are a vital late-season food source for numerous bird species, including robins and mockingbirds. While the ‘Nana’ cultivar fruits less profusely, its dense, evergreen structure offers critical winter shelter and cover for small backyard wildlife throughout the cold months. Planting this Yaupon contributes dependable cover and occasional sustenance across the seasons.
