Michigan Bulb doesn't seem to have the best rep on DG. Best be cautious.
My preference at this point in time is to only get named semps from reliable sources, such as members here or companies like SMG Succulents, Edelweiss Periennials and other listed in the forums. I would not purchase a semp generically described as "red" since they do not tell you the variety. Guess I'm becoming a semp snob!
Say it 5 times really fast: "Semp snobs seek special specimens specifically from perspicacious sources for spectacular snapshots"
(if you can...
