Osmanthus x fortunei 'Variegatus': 'Variegatus' Fortunes Osmanthus1

Edward F. Gilman and Dennis G. Watson2

Introduction

This large, vigorous, evergreen shrub or small tree grows 15 to 20 feet tall and forms a dense, round or oval silhouette. Very old specimens form a spreading vase. A hybrid of Holly Osmanthus ( Osmanthus heterophyllus ) and Fragrant Tea Olive ( Osmanthus fragrans ), Fortune's Osmanthus has the spiny, holly-like, dark green, white margined, leathery foliage of one parent plant and the extremely fragrant white flowers of the other. Frequently trimmed into a hedge or screen, Fortune's Osmanthus could be used more as a specimen or container planting, and the barbed leaves also make it suitable as a barrier planting. `Variegatus' has a nice appearance for a variegated plant.
