It will be seen by the following from the Journal of Horticulture, that this very sweet and popular plant can be grafted on the privet:
"Olea fragrans is flowering in the Economic house, at Kew, and possesses a perfume of the most delicious description. The flowers are small and of a pale yellow color, but grow many together in numerous clusters. They are used in China for scenting teas. That called pekoe is a green tea much prized for the scent imparted to it by - these flowers. The species is well worth growing in conservatories for its perfume. It is easily grown and succeeds on its own roots, but is perhaps hardier grafted on privet. A plant so grafted has withstood the last two or three winters against a wall."
