There are male and female plants. There are male and female king sagos, as there are both sexes of queen sagos. For there to be fertilized seeds, there must be a male and female plant in relatively close proximity. In addition, some cycads have very specific insect pollinators, which may not be present if the plant is grown in an area where it is not native. Another deterrent to propagation is that the seeds, because they are toxic, are not picked up and spread by many animals or birds.
Most seeds end up falling near the parent plants.
And the seeds may take months, even years, to germinate, and the plants are among some of the slowest growing in the world. For these reasons, many cycads are available only to and through collectors. Eventually more will be available. Zamia floridana, the sole Florida native cycad, reaches a height of 18 inches to 3 feet, is tolerant of cold, and grows in sun or shade, as long as the soil is well-drained. Use it as a ground cover, border plant or small shrub.
