Answer: If the rhizomes you planted where small, they may need to mature a bit before they will produce. When planting, place the rhizome just below the soil surface and barely cover with soil. They should be in a sunny spot and receive regular watering so they'll form roots. You can fertilize as soon as leaves begin to show. Use a 5-10-5 formulation. If they don't bloom this year, dig them up and replant them, making sure they're not planted too deeply.
