They're characterized by their large green leaves round blossoms. Although the most common calla lilies are usually white, they can also grown in pink, cream, yellow and red. Calla lilies make excellent houseplants. If you plant and care for them indoors, they can bloom year-round. Does this Spark an idea?

Put a little potting soil in the bottom of your pots. Slowly pour in water and mix with the trowel. Fill the pots up two-thirds of the way with more soil.

Place the bulbs, also known as rhizomes, on top of the soil with the growing end up. Plant one bulb per pot, or plant up to three together. Cover the bulbs with the rest of the soil so that the pots are just below full.

Water your pots thoroughly and place them in a warm room. Sun and light levels don't matter at this stage of growth.

4
Water the soil consistently so that it's always moist, but not quite muddy. Wait for the first shoots to sprout up.

5
Place the calla lilies by a window once they've sprouted. The ideal location is a south-facing window that gets several hours of light per day.

Continue to water the sprouts and monitor the light levels. You should see the first blooms in about six to eight weeks.

Keep the plants healthy and beautiful year-round by feeding them bottled fertilizer. Since all fertilizers are different, you'll want to follow the exact directions on the bottle. With these extra nutrients, the bulbs will be able to thrive without the periods of rest they would get in the winter during natural outdoor growth.
