Our oldest, 21 year-old Cycas taitungensis finally decided to flower this year, but it waited until three months after all the other cycads had finished coning. Plants in the genus Cycas are dioecious, with male and female cones on separate plants. Our specimen turned out to be a female, and by the time we finally located pollen on the west coast and had it flown in, it was too late to have meaningful sex this year. At least we finally know what sex we have. Let’s hope it gets back on a more normal schedule in the future.
Last year, we were thrilled when one of our cycads produced a female cone…a first for JLBG. We subsequently impregnated it with pollen supplied from the garden of one or our former volunteers, Mike Papay. Our plant produced a great seed crop (56 seed), which was recently planted.
As a point of reference, I should mention that cycads are dioecious…each plant is either male or female. The genus cycas is one of the oldest known surviving plant genera, having emerged between 250 and 350 million years ago, when it diverged from ginkgos. Cycas, having been around for a very long time, also have supercharged, swimming sperm…a trait not seen in modern plants.
This year, we welcomed our first male cycad to cone. The first photo was taken 1 month prior to the second photo, so it’s taken that long for this males’ cone to grow from a tiny bulge to be ready to spread its pollen (sperm). Since we don’t have any flowering females in the garden this year, we’re shipping off the pollen to a palm and cycad breeder in Georgia. This afternoon, we used the Lorena Bobbitt technique to sever its cone, which is now boxed (bottom image) and leaving town before the plant rights groups find out.
