Fun Facts

🌱 Dwarf Holly Compacta is a cultivar of Japanese Holly (Ilex crenata), not true holly (Ilex aquifolium), and its tiny leaves resemble boxwood more than traditional American or English hollies.
🌱 Both male and female plants are needed for berry production; a single male plant can pollinate multiple female plants in the vicinity, so a ratio of 1 male to 3-4 females is recommended for optimal fruiting.
🌱 This shrub can live 50+ years with proper care, making it an excellent long-term investment for landscape design that often outlives the gardener who planted it.
