Caladium bicolor aka Caladium

Taxonomy ID: 321

Caladium bicolor, or angel wings, belongs to the arum family. It grows from tubers and lives for more than one year. Its native range runs from Central America to Salta, Argentina. It comes from wet tropical regions and grows in shaded, fertile ground. Gardeners grow it for its leaves, rather than its flowers. It suits beds, shaded borders, pots, and indoor displays. In cold places, gardeners often grow it as a summer annual.

Plants form clumps about 1–2.5 feet [0.30–0.76 metres] tall. They can spread to 2.5 feet [0.76 metres]. Another account gives a height of 2.6 feet [0.80 metres]. Long, upright leaf stalks rise from the tuberous base. The leaves have an arrowhead shape and smooth, sometimes wavy edges. Green leaves carry patches of white, pink, or red. Their veins may show a different colour from the blade. Leaves can reach about 1.6 feet [0.50 metres] long.

Flowers are rare and often hide beneath the leaves. A pale green or yellow-green spathe wraps around the spadix. This flower structure adds little to the garden display. The fruit also has little value as an ornament. Summer is the main flowering season, though one source lists spring and fall too. The leaves provide the main show through the growing season. They die back in winter, which can limit the plant's value indoors.

Give plants moist, rich, acidic soil that drains well. They grow in partial shade and can tolerate deep shade. Bright shade or filtered light suits them well. Direct sun can burn the leaves. Plants need ample water while they grow and dislike dry soil. The listed hardiness range is USDA zones 9–10. In colder places, lift tubers after leaf dieback or the first frost. Store them dry at 45°F or above. Shelter the leaves from strong wind.

Serious pests and diseases are not major reported problems. Slugs and snails can chew holes in the leaves. Wind and hail can tear the thin foliage. Sap may irritate skin, and swallowing plant tissue can cause illness. Symptoms include mouth swelling, burning, nausea, vomiting, and diarrhoea. Pets and livestock may suffer fatal poisoning. One reference records fruit as food and describes traditional medicinal uses. These reports do not establish safe home use.

More information about Caladium

How difficult is it to take care of Caladium

Caladium requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.

What is the growth pattern and size of Caladium?

New growth will sprout from the top of the plant as it grows upwards.

What is the region of origin of Caladium

What are the water needs for Caladium

💧 Moist
Caladium should be watered regularly, allowing the soil to dry out between waterings.

What is the right soil for Caladium

pH: Acidic
Caladium loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

What is the sunlight requirement for Caladium

To ensure optimal growth, the Caladium prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

What's the right humidity for Caladium

The Caladium is not in need of supplementary humidity. Most water is taken in by plants through their roots, thus soil watering is the most efficient way to provide humidity to your plants.

How to fertilize Caladium

The Caladium should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.

Is Caladium toxic to humans/pets?

Caladium is poisonous if ingested. We suggest keeping this plant out of reach if you have children, cats, or dogs in the home.

Is Caladium flowering?

🌸 Summer; rarely flowers
If you provide your Caladium with adequate amounts of sunlight and water, it will bloom.
