Leucadendron plants have separate male and female plants, as opposed to normal flowers that have male and female organs in each flower.
The female plant has a cone, and is sought-after for cut-flowers and ornamental garden plants. The male leucadendron has a flower designed to spread pollen via its pollinators (either insects, wind or birds).
Leucadendron rubrum: This conebush is called the 'opregte tolbos' because the cones are shaped like a spinning top. It is pollinated by the wind.
