Guide to Growing Angel Wings and Elephant's Ear

Members of the Caladium genus are half hardy perennials and bulbs, but as they can not tolerate frost they are usually grown as ornamental annuals by gardeners.

They are a commonly grown house plant.

They are also known by common names such as Angel wings, Lance-leaf Caladium, Heart of Jesus, Elephant's Ear and Mother in law plant.

Caladium plants can reach a height of 30 to 60 cm and are grown by gardeners who prize their variegated leaves, which are often striped red, green or silver.

Plants like to grow in hot areas and are ideal as both a container plant or when grown in mass in beds and borders. They are a very useful plant for adding season long color to shady parts of the garden.

Caladium plants do not have a flowering season; they are grown for their wonderful foliage; leaves may be heart or lance shaped.

    How to Grow Caladium

    How to plant Caladium bulbs - If planning to grow Caladium plants then it is best to grow from tubers, these should be buried at a depth of 5 cm in the spring.

    If you have seeds they normally take one to three months to germinate at a temperature of 24 to 29 degrees Celsius.

    If growing from seeds (only in warm areas, with no chance of frost), then they should be used fresh and once sown lightly covered with topsoil. Caladium seedlings should then be put out with a spacing of around 20cm into a rich acidic soil in a sunny part of the garden. Although best foliage color is produced when grown in sunny areas of the garden, these plants are also attracted in shady parts of the garden.

    Caring for Caladium plants

    Caladium care is pretty simple: plants need to be watered regularly during the summer. In very cold areas it is necessary to remove Caladium plant tubers out of the soil and take indoors (store in sand) at the end of autumn to protect them from deep frost. Propagation is best in the spring, split the tubers, ensuring that each new tuber has at least two eyes.
