If you find a package that you like they should say what plants come in it. Write them down and post a WTB thread on the S&S. That is by far the best way to get plants. You will recieve better looking plants and more, for less money.
Yeah... maybe maybe not. There are dozens of places to buy plants from on the internet, and most of them do a good job most of the time. I'm actually amazed at the prices people get away with selling in the forum sometimes.
Shop smart. Do a little research. Find out what type of plants do best for the type of set up you will have. The nice thing about buying all the plants from one qualified source is you get everything you need, and exactly what you want quickly, and if you can contact someone at the place you are buying from and they are knowledgable about the plants, they can help you to pick out the right plants.
Mostly what you will find in the forum is stem plant cuttings, and some foreground plants. You may want to stay away from most stems if you are not going to have C02. Any sword plants, Cryptocorynes, java ferns or other water ferns, Anubias, Crinums, Vallisneria, Sagittaria, Aponogetons should do well with moderate light, and maybe even low light. These rooted or bulb plants often come potted where they are very well rooted and will get a good start in your aquarium.
Here's a nice plant package:
Yikes! You would seriously reccomend those plants to a beginer who is not planning to have C02? Seriously? Half those plants are considered difficult even with high light and C02, and I dont think most of them would last a month without C02. I hope you didnt buy it. Seriously dude
