That would be B. caroliniana and B. monnieri. There may be a little B. salzmanni in that one but I mixed all the Bacopas together, so I'm not sure. I will get an ID from my suppliers!

Looks like mainly B. caroliniana, but i think you're right about there possibly being some B. salzmannii hidden in there.

Looks great Kiran! Do you plan on putting sand at the bottom?

While i like the plants that you've placed around the WK ball, i feel like it destroys the Wabi-Kusa look. Though, now that i think about it, i guess submerged WK balls typically don't retain the same style as their emersed counterparts. Looks nice though, Kiran!
