This plant doesn't mind hard water, prefers bright light, and a good substrate, water column ferts are a plus. If it is healthy it does not notice that it has been trimmed, nor will the lower leaves turn black in a thick planting. The concept of it prefering cool water is only for people who want to keep it longer than a year, 72 or under like Wö£fëñxXx has it growing. The idea is to keep it in 'spring' conditions, if you let it get to summer conditions it will switch gears after a while and crap out. Yes it will grow in warmer water, yes it will look fine, but eventually its genetics decide summer must be over and it goes into it's fall die back.
I had the best growth of this plant when I kept it at a 10 hour day, when i jumped the tank up to 12 hours it looked great for 3 months and it died back, after 2 years of really nice growth and color.
Aquascape? I'm a crypt farmer.
It's a fine line between fishing and standing on the shore looking like an idiot.
That IS an aquascape, it's titled "The Vacant Lot".
