I just already answered your light post, this is the first important step, to make sure you have a light in the tank that will be next to ideal for the plants.
Then really the selection of plants depends on 2 things 1) Tank size? 2) Fish in the tank?
I don't necessarily thing the "Beginner plants" above are the only thing you can have. I'd love to help recommend you some if you could answer the 2 questions above. I'd not wanna recommend you plants that either outgrow your tank in few weeks and/ or plants that would be destroyed by the fish you have
As for maintenance: Many people on here use fertilizers to help plants grow. I personally don't and mine are thriving well, all depends on your source water and light really.
Leaving the only 'real maintenance' which is trimming plants back if they get too large, which is mainly stem plent, you cut the top's off, stick them back in the gravel and watch them grow
So really its nothing that takes a lot of effort, but it sure looks cool IMO
Here's a few new pic's of m newly set up planted tanks http://www.tropicalfishkeeping.com/f...ew-pics-33450/
Last but not least your substrate is important: Large grvel does not really help a plant to develop a healthy root system, while finer gravel or sand does - So what you got in the tank
