wet habitat terrestrials for culture in water

[hydrophyte]

Hi there,

I am a new member. I have already received several warm welcomes. Thank you!

I have a small growing collection of miniatures, as well as a second area of interest. I am trying to grow orchids in fishtanks. I have made a little headway in this effort, and mention a few points in a thread that I recently started over in the Terrariums forum.

I am interested in finding out about more species from wet terrestrial habitats for potential use in these systems. I realize that a wide range of varieties/species have proven suitable for semi-hydroponic culture, but the general idea for my aquarium displays is that they roughly approximate wetland/riparian habitats in nature, so epiphytic orchids are not really suitable. Furthermore, the plants in these enclosures have most of their roots fully underwater all of the time.

Can anybody recommend any promising varieties or species? And sources? I am currently growing a Phragmepedium 'St. Ouen', Spiranthes odorata and several different Bletilla. It is rather early to assess the performance of these plants, but they are all growing in the described conditions. However, I have found that this phrag does not tolerate having more than 1/3 of its rootball underwater.

Since these are intended for year-round display. I think that tropical and subtropical species are preferable. I anticipate that I might have some trouble accomodating the dormancy requirements of my temperate plants, and I will have to remove them from their displays.

Any suggestions at all would be greatly appreciated.

Regards,
