I got the HU one Al's first picture. They are aslo called Giant Baby Tears. They are the one that grow up and not like HM that are runners. I also got what Ed is looking for, the Becopa. They so many different type of them that looks the same. LOL
I know that they sell Baby Tears HM at Pacific for like 4 bucks for a few stems. They used to hand out wads for 2.50 back then.
I actually started growing mine from 2 small little pieces that got mixed into my java moss. But I still don't have much because i don't use ferts and I'm using FSS, I love these plants. I like these better than HC
You already have it. It is exactly the same as Hemianthus micranthemoides, though micranthemoides has now been proven to be an erroneous name. The real micranthemoides has not been seen for over 70 years.
