Hapenaria repens is said to be an aquatic orchid, but it's not technically aquatic. This one grows naturally in bogs so it's not really fully aquatic. BUT, it loves water and it's pretty much impossible to over water; PERFECT!
So here is my solution! I took a nice glass fish bowl (don't tell my mother, but it's one of our vases for wedding centerpieces

)
For the bottom layer, I put down some sheet moss from one of my orchid show displays.
Next I added a few Habenaria repens.
Finally, I took some real aquatic plants ( growing in their emersed form) and added them.
I keep everything a little bit of water in the bottom of it at all times, so that everything stays nice and wet.
Here's a list of the plants:
Habenaria repens
Sheet moss
Glossostigma elatinoides
Hydrocotyl Sp. Japan
Eleocharis acicularis

Also, I threw in some Bletilla striata seeds from the pods I harvested from my garden this fall, and THEY GREW!
