    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.
