I got the plant in a trade back in September of 2019, it is still living and I have in two different locations. I show no record of it blooming yet. I do hope to post photos next year. I have it in a pot and in the ground and it still appears healthy.
I got 'Cow Bird' in a trade with Karen and Rodger here on the forum back in Feb. 2021. I now have it in two different places. I don't think I have had any seedlings from it, but I am sure I have tried because I do like the plant. I see it has no child plants listed, so maybe it is not pod or pollen fertile? I have not recorded any stats.
Here are what the two clumps looked like this morning.
