Ever seen those fantastically landscaped aquariums that seem to have both land and water in one tank? These are the types of plants that work with a paludarium "swampland" set up!
Bella palm (sometimes called the Parlor palm) is the species "Chamaedorea elegans".
You'll love this tropical, upright foliage to add height in your arrangement!
Easy care, and undemanding, these are wondrous plants that will survive two weeks without a watering (should you choose to keep them in a pot).
They are equally at home in a bog, or Paludarium hybrid set-up, however! They should NOT be completely submersed into water.
Bella Palms need a bright window, without direct sunlight. You'll scorch the leaves in a sunbeam! Mine do very well under a covered porch in the summers here in Kansas.
If you'd like to transition these to a swamp or boggy tank, I would suggest slowly acclimating these guys to a much more damp environment over a matter of weeks. Water daily, so the plant gets used to having a lot of water around. Perhaps place the pot in a shallow few inches of water in the last few days. Finally, remove the plant's roots from the potting soil, and giving them a gentle wash before landscaping in your paludarium set up!
As in the sample photos above, there will be some variation in size and branching. It's just the nature of the beast. The ones I send to you WILL be healthy, happy, growing merrily, and be ready to plant!
