Cinnamomum camphora (Camphor tree) is the best known species under the camphor trees of Asia. Camphor is used as a spice and as medicine. Also as an insect repellent substance. The plant thrives well with us as a houseplant and has quite large, ficus-like leaves. It is great to occasionally pluck a leaf and smell it.
You can sow Cinnamomum camphora throughout the year. Flood the seeds with water of around 85 degrees Celsius. After 10 seconds pour cold water over them. Keep the seeds in the water for a few days and refresh the water daily with lukewarm water. Sow then in a loose seed germination compost. Cover the seeds with a layer of seed compost 3 times the thickness of the seeds. The optimum germination temperature for Cinnamomum camphora is 25-35 degrees Celsius. Cover the tray or container with foil, glass or a transparent cover to prevent dehydration.
