Pinellia pedatisecta, a plant with high invasive potential

The aroid genus Pinellia includes two species with the potential to be invasive plants under our local conditions.  These are P. ternata and P. pedatisecta. In the image above you see the inflorescences of P. pedatisecta. What you don't see are the propagules deep down inside the spathe. In a few weeks those I did not pick will shed these propagules and soon another dozen or two of this plant will appear.

I've called these propagules because I'm not sure just what they are. Are they seeds? Are they produced parthenocarpically? I don't know, but whatever they are, every one seems to grow.

These plants are interesting, but I suggest you avoid them and never plant them in your garden.
