Yue Yue Hong (monthly red) is a cultivar from Guangxi province. A naturally occurred mutation; it is the only four-season O Fragrans with orange/red blooms. It is a shrub/small tree of up to 5 meters. Their leaves are shiny but narrow. Some leaves have smooth edge, others have saw-like edge. In normal climate, it blooms 100 days each year.

You have an osmanthus growing indoors? I have one planted by my back door. It blooms intermittently throughout the year, and I love to smell the blooms when I go into my back yard.
