Pink Calla Lily Plant Care

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.

  1. Pot the rhizomes in a 6- or 8-inch pot, covering with 1 inch (2.5 cm) of soil.
  2. Water thoroughly and empty drainage tray.
  3. Set your potted bulbs in a warm, sunny window. These colorful callas won't bloom unless the temperature is 70°F/21°C or higher, even at night.
  4. Keep the soil lightly moist until you see the first bit of green leaves poking through the surface. Gradually increase water as the plant grows and blooms. (Flowering plants are thirsty, so don't be stingy with the H2O.)
  5. Fertilize only while plant is growing and flowering.

How to Get Pink Calla Lily to Re-Bloom

This beautiful plant will bloom for 4-6 weeks, then can be brought back to bloom the next year. Here are the steps:

Give 'em a rest

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.

  1. When flowers die, allow the plant to go dormant by gradually reducing the water.
  2. Wait till the foliage turns yellow and withered, then cut it back. Leave the rhizomes in the pot and store them in a cool (40-60°F/4-16°C), dark place giving it just enough water to prevent the rhizomes from drying out completely.
  3. Dormant rhizomes can be restarted in January to March. Pot them in 6 in (10 cm) pots with fresh soil. Top with about 1 inch of soil to cover the rhizome. Put the plant back in a warm, bright spot (out of direct sun) and keep the soil moist. Blooms should appear in about 8 weeks.

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.

Pink Calla Lily Care Tips

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.
