Osmanthus fortunei Carrière, Rev. Hort. (Paris) 1864: 69 (1864) (syn: Olea japonica Hassk., not validly publ.; Osmanthus aquifolium var. japonicus (Siebold ex Makino) Makino; Osmanthus fortunei var. cordifolius Carrière; Osmanthus fortunei var. latifolius Mouill.; Osmanthus fortunei var. ovatus Carrière; Osmanthus japonicus Siebold ex Makino);
Leaves do not match as per images at Dave’s Garden Plant Lust Kiefer Nursery
But no variety is mentioned here.
That is all I got.
I hope it is Osmanthus × fortunei Carr. a hybrid of Japanese origin between O. heterophyllus and O. fragrans
