I was in Petsmart on Sunday getting my dogs nails clipped and I wanted to check out the fish isle. I noticed they were selling plant bulbs for less than 3 bucks. Inside the packs were anywhere from 4-6 bulbs of various plants. I wanted to buy them because they were cheaper than one plant, but wasn't sure if bulbs were hard to grow or they needed special requirements. I don't remember the types of plants they were, but if they are anything like regular plants, I'll go back and buy some. Any ideas?
