Ordered the rest of the plants today for the back, these will all grow emersed so will have a good start on the root system before the flood:
10 -Diandra (Didiplis diandra)
10 -Rotala Magenta (Rotala macrandra v. 'narrow leaf')
10 -Rotala Wallichii (Rotala wallichii)
10 -Mayaca (Mayaca fluviatilis)
5 -Rotala Indica (Rotala roundifolia)
lots of colors in these, reds, orange, greens.
Also got the mosses tied to the trees, I'll update with pics once everything is in this weekend.
I'm shooting for June 1 for the flood.
