I checked on the progress of this local 'Blue Glow'. Mine is still preparing for bloom, probably slowed down by winter weather. Apparently no bulbils. Too bad!
There appear to be a few viable seed pods up at the top of the structure. What plant those might produce will be interesting. All 'Blue Glow', except the odd offset, are a tissue culture of one selected plant, are they not?
Beyond that blooming 'Blue Glow', a nice Aloe...ferox?
