Yellow Calla Lily (Zantedeschia rehmannii) is a waxy, long-stemmed variety that captivated Georgia O'Keeffe's attention in the '20s in her popular art piece. Observe the curves and unique blooms that hypnotically make you stare a little longer. We suspect the gods painted this one from a paintbrush dipped in the sun's rays. You may even have to wear your sunglasses when gazing at her!

Yellow Calla Lily Care & Buying Guide
In warmer climates (zoes 8-10), calla lilies grow well in partial shade (4-6 hours) to full sun (6-8 hours). In cooler climates (zones 3-7), they enjoy full sun.
Keep your Calla Lily consistently moist but not in soggy soil. Use filtered, bottled, or tap water that is sitting 24 hours to release the chemicals and water enough to discharge out of the drainage holes. Once the water is fully drained, replace it into the cache or decorative pot.
The Calla Lily enjoys and thrives in average humidity.
Comfortable room temperatures will help the Calla Lily to thrive.
Outside: Place in bright, indirect light if grown in a greenhouse and flowering so the leaves don't burn. Inside: Set in bright, indirect light.
Rhizomes planted in containers: Apply a liquid fertilizer especially formulated for flowering bulbs at half strength every two weeks in a container. Rhizomes planted in the garden: Add an organic fertilizer such as bone meal rich in phosphorus, calcium, and a trace of nitrogen. These nutrients will help the roots establish.
A soluble bulb fertilizer like 3-5-3 can also be apart of the soil amendments to give your bulbs a good start. As the foliage emerges, repeat the bulb fertilizer application each month until they start blooming. Stop when the Calla's start flowering to help extend the life of the bloom.
Cut the leaves back after the first frost when the foliage turns yellow. If you are in a cooler zone (3-7), remove the rhizomes from the soil with an inch of stem attached. Knock off all the soil and lay them on newspaper in a dry place for a week. Do not wet or wash the rhizomes. Sprinkle them with powdered sulfur to protect against fungi while they're in dormancy. Lay on a single layer screen or in a mesh bag so air can circulate around them. Store the rhizomes at 50°F-60°F.
When all chance of frost has passed in the spring, plant in the garden at a depth of 3 to 4 inches deep and 12 to 18 inches apart after the last frost in your planting zone. Place your rhizomes in a horizontal position, so the eyes are facing upward. Add compost or soil conditioners and mix in with the native soil.. Depending on the warmth of the soil, it usually takes 60 days to bloom.
If growing in a planter container, use a well-draining potting soil with perlite to aerate the soil. Add amendments to clay soils in the garden to aerate the soil and allow for good drainage.
Cut the leaves back after the first frost when the foliage turns yellow. Trim back faded flowers to the base of the stem.
Divide the rhizomes in the spring after the last frost in your planting zone. Plant each rhizome (type of root system) in a deep container at least 3-4 inches deep with soil underneath it for rooting. Set the growing tips facing upward. Cover with well-draining soil (add amendments to heavy soil in the garden). Wait until the plant is producing new green leaves before starting to fertilize. Stop fertilizing when buds form.

Yellow Calla Lily: Care Guide
Yellow Calla Lily care is easy, but there are several things to keep in mind. Follow these Calla Lily care tips for a lush and happy plant:
Watering and Humidity
Calla Lilies enjoy consistent watering, but the soil should drain well and never get soggy. Reduce watering during dormancy in winter. Use filtered water or leave tap water to sit for 24 hours to release the chemicals. Average humidity is sufficient for your Calla plant. Place the pot on a pebble tray to increase humidity in dry environments.
Light and Temperature
Yellow Calla plants grow best in indirect but bright sunlight. If growing it as an indoor plant, provide a location with 6-8 hours of full sun daily. Outdoors and in warmer climates, protect your Calla from direct sunlight as it can scorch its leaves. If your Calla isn’t blooming, try moving it to a sunnier location. Your Yellow Lily will flower better in bright, indirect light. The best temperatures for your plant are comfortable 50℉ - 75℉.
Soil and Repotting
Use a well-draining potting mix with perlite to enhance drainage and improve soil aeration. Avoid heavy clay soils. Potted Calla Lily care is simple; repot your Calla once yearly. Dig up the rhizomes of Callas grown in the garden after the first frost. Store in a dry place at around 50°F-60°F until next spring.
Feeding and Propagation
Feed with a liquid fertilizer for flowering bulbs every two weeks. Nitrogen-rich fertilizers can prevent your Callas from blooming. Propagate your Calla Lily Zantedeschia by dividing the rhizomes in spring, after the last frost. Then, plant each new rhizome in well-draining soil.
Pruning, Cleaning, and Common Issues
Cut back the yellowing leaves after the first frost. Remove any spent blooms regularly. A Calla Lily with yellow leaves is either overwatered or too dry. Check whether the soil is dry before watering. When choosing Calla Lilies for sale, check for pests on the undersides of the leaves. Monitor regularly for pests like aphids and spider mites.
