Our Walmart has a whole aisle of bulbs because it's spring time. Last year, I planted their elephant ear which have done great. I also planted the tigridia and the dutch iris. They didn't do as good.
This year, they were selling northern bulbs and I somehow thought that for only $5 I can try to grow lily of the valley down here. The packaging clearly states "Gauranteed to Grow." It's got a picture of Florida on the back of the package and I followed all planting instructions.
So, I am already assuming these plants will fail, but then what? How will I collect on the guarantee? I think this is just a very good marketing tool because no one will ever try to collect on the guarantee. I do the same thing with gardening clippers. They last a year, then they break. I took a pair back to Walmart last year and they said I need to contact the manufacturer. The manufacturer's website did not provide any info that was useful. Oh well. :)
