Sorry, was going to take some pictures for you the other day but got rather busy.
Here are a few pictures of the false unicorn I have growing here in the beds.
You can see a couple plants with the seed stems and a decent picture of one that does not have a stem. It is the rosette in between the two stems
I tried to get a close up of the seed stem with my phone -not good. But, you can see that the seeds are on the stem and at the left you can see another stem. On the bottom right, (by the star) you can see a stem without seeds. I'm not really up on false unicorn that much, but I think this is the difference in male and female plants.
Here is a closer picture of the seedless stem in the last picture. You can also see the stemless plant well (with a mushroom under there). On the top left, you can see another plant that doesn't have a stem.
