Micron® Holly Shrub

Micron® Holly is the trade name for Ilex vomitoria 'Gremicr', a dwarf, slow-growing evergreen selection with diminutive leaves and a compact, mounding habit. Garden Debut lists it at 1–2 feet tall and 2–3 feet wide, with sun to partial shade; the patent describes this selection as hardy to USDA Zone 7 ([Garden Debut](https://www.gardendebut.com/plant/Micron-Holly); [U.S. plant patent](https://patents.google.com/patent/USPP21168P2/en)). ## Form and placement Use its low, rounded evergreen form for a compact border or foundation accent, or as a single specimen in a large container. The exact selection is much more compact than typical dwarf yaupon holly. Yaupon holly is native to the eastern United States and Mexico, and its species profile lists foundation planting and large-container uses ([Garden Debut](https://www.gardendebut.com/plant/Micron-Holly); [NC State Extension](https://plants.ces.ncsu.edu/plants/ilex-vomitoria/common-name/yaupon-holly/)). ## Growing conditions Follow the cultivar-specific recommendation of sun to partial shade. The broader species tolerates full sun through deep shade and a wide range of soil types, but this small selection has a more specific seller recommendation. Water new shrubs regularly during establishment and mulch around the root zone to conserve moisture ([Garden Debut](https://www.gardendebut.com/plant/Micron-Holly); [NC State Extension](https://plants.ces.ncsu.edu/plants/ilex-vomitoria/common-name/yaupon-holly/)). ## Maintenance Micron grows slowly, so let the naturally compact mound develop before shaping. Yaupon holly tolerates pruning, but this dwarf selection generally needs only occasional light trimming to maintain its outline. Remove damaged or wayward stems as needed and keep mulch away from the stem base ([U.S. plant patent](https://patents.google.com/patent/USPP21168P2/en); [NC State Extension](https://plants.ces.ncsu.edu/plants/ilex-vomitoria/common-name/yaupon-holly/)).
