I have also found great plants at E&L Pets. Their dwarf hairgrass has worked out pretty well for me.
Its a shame Petsmart doesn't get a decent system to support freshwater plants. It wouldn't require much money to buy a couple bulbs and some dry fertilizers.
Ah yes but we're a corporation and have very strict layouts we have to stick to. I wish we (the employees) had a say in the matter, but no. Each store is merely a clone of the others...with size and hardgoods being about the only differences. (ok that's an exaggeration, but none of the petsmarts I've been in from IN, KY, TX or CA have a decent plant selection XD)
Haha maybe I'll start updating every Friday when we get our fish/plants if something cool comes in the assorted potted plants.
