Botanical Name: Zantedeschia rehmannii
Pink Calla Lily has become favorite house plant, and it's easy to see why!
Its charming, funnel-shaped blooms may be pink, rose, lavender or violet. It is a smaller plant (growing up to 16 in/40 cm) than the white or yellow varieties ... and I think much more attractive. Those long, tapered leaves are deep green, often with faint white spots.
They fall under the category of "tender bulbs" because they can't tolerate freezing temperatures. But that makes callas easy to please indoors.
You'll find these petite pink callas for sale in nurseries and online flower delivery sites in late winter, spring and summer. You can now buy lilies in florist's shops around the holidays, too.
The secret to keeping its blossoms fresh for several weeks is to keep the plant warm and well-watered.
Soooo...you've purchased your Zantedeschia rhizomes and they're still in the bag. Wondering what to do next? Relax. They're easy to grow. Just keep them warm and moist and you should see those colorful calla blooms in about 8 weeks.

This beautiful plant will bloom for 4-6 weeks, then can be brought back to bloom the next year. Here are the steps:
Flowers are triggered by a cool, dry dormancy for at least 2 months. With this rest, you can force your callas to rebloom for 3-5 seasons. When rhizomes stop producing a good show of flowers, it's time to replace them.
CAUTION: All parts of calla lilies are poisonous; the rhizome is the most toxic. Keep it out of the reach of children, cats and dogs who may play with or ingest this plant.
Origin: South Africa
Height: 12-16 in (30-40 cm)
Light: Bright indirect light
Water: After potting pink calla lily rhizomes, keep the potting mix lightly moist. Increase water when plant is growing and blooming.
Humidity: Average room (around 40% relative humidity). Indoor air can become extremely dry, especially when windows are closed up and the furnace is running. It's a good idea to use a humidity gauge, rather than guess. The easiest way to boost indoor humidity is to use a cool-mist room humidifier. It is low-cost and your tropical plants will love it.
Temperature: Warm (70-85°F/21-29°C) while growing and flowering. Keep plants away from heat/AC vents.
Soil: Peat moss based potting mix with added perlite for faster drainage. African violet potting mix is ideal.
Fertilizer: Feed every 2 weeks with a high-phosphorus liquid fertilizer diluted by half while plant is growing.
Propagation: Rhizomes. See how-tos above for planting rhizomes.
