Be very careful about the other plants that are sold in those things. Only 3 or 4 of the species they sell like that are 'true aquatic' plants. Many of the swords are 'bog' species. I believe the only ones they sell like that that will do well in an aquarium long term were the Tropica Fern (aka Java Fern), Amazon Sword (not brasil or Borneo, those 2 will just die in 2 months or so), and Wisteria (though i think they called it something else) though there may be some more, those are what i can recall off the top of my head.
Also, due to the drier nature of the packaging and that it is hung on a shelf with no lighting besides whatever hits it from our MH ceiling lights, these things have a very high mortality rate, so check them out carefully before you pick one up.
As a petco employee, I can also say that they are going to phase out their live plants that we get that arent in those prepackaged things
Although the only live plants we get are Anubias azureas (sp? large smooth leaved anubias) your basic amazon swords, H polysperma, a crypt every once in a blue moon, a bunch of bog plants like draconia, and bunches of elodea and wisteria.
I have been in contact with several higher ups about this issue, so we will see what becomes of it. Most likely nothing.
