I too purchased these bulbs at a Walmart. I planted them late in a raised box next to a concrete wall facing south. I should mention that we are in zone 4! Much to my delight, they not only grew approximately 28" tall, but produced 3 lightly fragrant flowers per stem! It is now late September and we have had several frosty nights already. Since the foliage is still so green and hardy, I will most likely wait until mid October to up root them and store them until planting in late May, early June of 2013. They received no special treatment and were quite wet most of the summer as we have had an unusually high amount of precipitation, however, that being said, it is now extremely dry so I did water them this past week. Their survival will be dependent on their winter storage. Will let all know how they make out next spring. Mmmmm, I think this plant will grow anywhere! Cheers!! onthelevel, Edmonton,Alberta, Canada
