My small grafted plant shows the first bloom. Color is in medium gold. Petal size is rather large, about 4 times larger than that of an average Osmanthus( possibly due to the nice condition in my green house).
Very likely it is of 4-season type Osmanthus. Fragrance is wonderful. Jin-Mon-Tong means Gold-Filled-Living Room.
