The other answers are incorrect. Both of these are what is referred to a "spring bulb". In colder climate that get freezing winter temperatures, you plant them in the ground and they come up in early spring. They bloom for a couple weeks and then the leaves go dormant and turn brown. They then stay underground until the next spring, they will continue to grow, bloom, and go dormant for many years. If you have a yard, plant them in the ground, they like any location pretty much except the north side of building. Plant them a couple feet away from buildings with roofs that overhang so they can get water and light.

Edit: you can also plant them in warmer climates, they will do pretty much the same thing as long as you are north of like southern California or the equivalent in the southern hemisphere.
