Hello Paul,

On my trip to Wilson Botanical Garden in Costa Rica last year, I saw these plants (pictures attached) growing on a damp wall exposed to sunlight. I recall that I also saw begonias, but I couldn't find pictures.

A friend advised that this list sometimes discusses water walls and the species that suit them.

I have a new water wall.  It's about 5 feet high and about 20 feet long.  Rocks are already turning green after just a week of water including several dry spells (to fix leaks!).  I live at 1400 metres above sea level in the Dominican Republic so day temperatures can be as high as 32C (often cooler) and nights drop to as low as 6C.  The wall is exposed to strong sunlight for several hours a day.  The water is neutral and direct from a river.  The rocks are probably neutral (but may tend towards alkaline - I must test this).

If anyone can suggest specific plant species or varieties (not necessarily aroids) that would be either interesting or attractive, I'd be grateful.  I'm relatively knowledgeable about carnivorous plants  and not new to specialist gardening, so I'm  looking for something a little more helpful than generalities (so for example, being told that "ferns" are good would be no real help).

Thanks for any suggestions, especially if replies are copied directly to me.
