Well in this case it was given to me as 'pearlweed' and the person who gave it has no clue what it is other than that name; having said that I'm finding more and more that scientific names are frequently changing (esp with dwarf cichild) where things are reclassified multiple time over a relatively short period of time.I think I've grown "pearlweed" a few times now but I think it was called HM (hemianthus micranthemoides, afaik...This is why I hate common names sometimes. At least with latin names you'll be closer to what they're called lately, lol.
Of course guppy grass is not close; but the sender thought it was and i knew better as I noted above. HM. Isn't that a clothing store ?HM is a much shorter name than pearlweed . There is a oldish plant club member who continues to call it pearlweed even though he knows better, lol.
Guppy grass is not even close to anacharis. Well, maybe if happy, they can both grow like crazy!
I have no clue - i never buy pearl weed; my goto plant is hornworth since i know how ot grow it; having said it i do admit that pearl weed is 'softer' and that might be beneficial for some fishes - certainly my snail which never touches horn worth will munch pearl weed....Might be a "kids" clothing store, lol.
Isn't there another plant that's similar to HM? I can't remember the genus...starts with M I think...Oh, a quick goolgle & it's the same as HM. Micranthemum micranthemoides, all this time I thought they were different, huh.
