Here are all great practices that will enhance the beauty of your osmanthus.
It is best to plant Osmanthus in fall to speed root development up over the winter.
But like most shrubs purchased in containers, you can plant it all year long as long as you double down on watering if planting in spring or summer (avoid times of very hot weather).
As a hedge, space the base of each osmanthus stem more or less by 6 ½ feet (2 meters).
Propagating osmanthus
Cuttings are the fastest manner of multiplying this shrub. Go ahead and multiply your osmanthus in summer!
Pruning isn’t a definite necessity for Osmanthus, but, nonetheless, it helps keep a dense, tight bearing all year round.
Osmanthus can’t cope with deep cold or with sitting water, which is why you’ll have to protect it.
Osmanthus isn’t a very common shrub, but it does have many advantages that other shrubs don’t have.
Its magnificent green, sometimes mottled leafage (depending on the variety) is very dense, and it is perfectly suited to flowered, not-so-tall hedges.
Its white flowers and deliciously fragrant flowers remind one of the smell of jasmine. In China, its flowers are used to flavor green tea.
Osmanthus is also called false holly because the leathery leaves are similar to those of holly, even if they aren’t spiky.
Lastly, you should know that if you hope to grow Osmanthus in a pot, nothing should stop you because this shrub is perfectly suited to growing in pots and containers.

Osmanthus fragrans (orange flowers): I live on central Vancouver Island (PNW classification) where it’s the mildest in Canada. We do get a few frosty days/nights in some years. This plant is sensitive to cold winds (literature) during flowering. We get rain and sun in the autumn, heavier rain in winter, and more sun and less rain in spring.
Could/Should I plant it in the garden and wrap it with insulating cloth during the colder season? Or … how about a reasonably large planter that may be wheeled into the area of the front door when cold?
This plant is not normally sold in our area, but I believe it can be available. I’ve had good success with Osmanthum Goshiki.
