Bought this one in the fall of 2016. It bloomed in '17 and '18. Not the highest bud counts, but it has sturdy scapes, is fertile both ways and self fertile. Since I don't have a lot blooming in the beginning of June, I've selfed it and gotten nice pods with good seed counts. The seeds collected in '17 are nice sized seedlings this year. Not much for increase, three big fans in my clump. I did note that LF will make short runners and can pop up new fans a few inches away from the mother clump. I broke one off that had a three or four inch rhizome with a slender 4 leaf fan. So next year Ian should have a report for Lava Flow...
