It's a beautiful plant. Yes it is manageable and easy to find.
You can by it at Aquabid, or any online plant store. You can also try certain forums that have a sell/trade section. Many people have this plant for sale, or for swap. You can request it if you don't see any posts, and more than likely, someone will answer you.
IME, this plant requires at least 2.5 wpg with co2. It does much better with a little more light, but co2 is a must.
When you prune the grass, make sure to turn off your filter.
