Oh Chris, what a wonderful treat to find out in your semp beds. Great photos. Will be interesting to see if you can select out offsets that will retain this unusual feature. I agree with Kevin and twit, about using any blooming plants for breeding purposed, just to see if you can isolate the trait.
Kevin, sure would have loved seeing the Stars and Stripes.
Now that I am back home, I will have to go through my beds to see if there is anything unusual going on.
