Hello! I have a paludarium (an aquarium with a land area above) that is meant to simulate a hill stream in the Himalayan foothills. Right now I have a huge variety of terrestrial mosses, most of which are thriving, and some rice plants. I have had a couple of tea (C. sinensis) seedlings, but they are just barely surviving, and I don't know how long they will last. I'm looking for a replacement.
The planter is about 3" wide, 7" long, 2" deep, lined with stainless steel mesh on the bottom so roots can grow directly out into the acuarium water a few inches below. Substrate is sand. A trickle of water flows in at the top, drains through the sand, and into the aquarium. Environment is fairly humid, and misted several times a day.
I'm looking for a plant that can be kept very small (less than 6" tall), that is OK with wet feet. If it looks similar to Camellia, that's a bonus. I think creeping jenny might fit the bill, but I'd be interested in some ideas from the experts. Any recommendations?
