Botany Photo of the Day will have brief written entries on weekends, holidays and my vacations from April through September. – Daniel
Thank you to “ginger749” on the UBC Botanical Garden Forums for submitting this photograph from Gold Coast, Australia (original image in this thread).
In another example of a misleading common name, sago palm is a cycad, not a palm. The Palm and Cycad Societies of Australia has a factsheet on Cycas revoluta.

male?

Male or female? In many cycads we would normally have to wait for the cones to start emerging, the male cone being more slender and possessing a greater number of smaller sporophylls than the female. As the cones mature, sexing becomes easier as the pollen sacs become visible under the sporophylls of the male: his opposite will be producing a larger cone but with fewer sporophylls under each of which would be two to eight ovules. In this example of C. revoluta however, I believe the photograph is showing a female about to flower (if it were a male, the shape would already be distinctly cone-like). Once pollinated she will close and start to form seed (usually during the Summer) maturing from a yellow to a bright orange walnut size by the late Winter early Spring when the seeds will then be ready to be dispersed and start their 15 to 20 year journey into adult maturity.

I was cleaning out my flower bed the other day and noticed a strange yellow feathery ball forming on my cycad revoluta. After seeing this picture, I believe I have a female that is about to bloom. Does anyone know how long this process takes? Does it happen every year from now on? My plant is around 10 years old.

Can you tell me a little about this plant? I am lookinmg for a plant similar to this plant. I need the plant not to exceed 5' at maturity. It will be grown in an ocean atmosphere in almost full Sun.
The place it will be grown is in Dana Point, California
