Holly Osmanthus Holly-leaf Osmanthus
Osmanthus heterophyllus
Oleaceae · broadleaf · introduced
Holly osmanthus is the evergreen shrub that looks like holly but is not, the spiny, glossy, dark green leaves mimic holly so closely that most people cannot tell the difference until they notice the opposite leaf arrangement (holly leaves are alternate) or catch the sweet fragrance of the small white flowers in fall. It grows eight to ten feet tall with a dense, rounded form that shears into formal shapes as cleanly as any holly. Native to Japan, where it has been cultivated for centuries.
In Western Washington, holly osmanthus performs well in sun to part shade with well-drained soil. It is slower-growing than holly but denser and more refined in texture. 'Goshiki' is the showpiece cultivar, new growth emerges in shades of pink, cream, and green before maturing to dark green, creating a multicolored, variegated effect. 'Gulftide' is a compact, dark green form for hedging. No significant disease or pest concerns are tracked. The fall fragrance is a bonus, subtle from a distance, sweet up close. For a holly look-alike that avoids the berry mess, adds fragrance, and maintains the same dense, formal evergreen presence, holly osmanthus is the refined alternative.
