Caladium Description

Caladium commonly called Elephant Ear, Angel Wings or Heart of Jesus bear striking arrow-shaped, paper thin and beautifully marked leaves.

The common colors are white, pink and red. This dazzling Caladium foliage only lasts a short time from late spring to early autumn.

Thereafter, the Caladium foliage dies and the plant goes dormant which is a natural characteristic of this plant.

Caladium grows from tubers which can be saved after the foliage dies to be replanted in the next year to propagate new plants.

Caladium Origin

The Caladium genus comprises of about 7 species which are native to South America and Central America and naturalized in India, parts of Africa and various tropical islands. They grow in the open areas of the forest and on banks of rivers and go dormant during the dry season.

Caladium Size

In the wild Caladiums can grow to a height of 1-2 ft, while the leaves can be 6-18 in. long and broad.

There are over 1000 named cultivars of Caladiums. In cultivation most cultivars grow to about 24 in. high and 24 in. wide, although there are dwarf varieties in cultivation now.

Ensure the pot has a drainage hole to prevent the soil from getting soggy as it can lead to root-rot.

Temperature for Caladium

Caladium (Caladium hortulanum) Propagation

Caladium grows from tubers which can be saved after the foliage dies to be replanted in the next year to propagate new plants.

Store the Caladium tubers in sand or sawdust at a temperature of between 15-320C .

Temperatures outside this range will cause damage to the Caladium tubers which will result in stunted growth of the plants.

The Caladium tubers can also be allowed to remain in the same pot until the next growing season.

Keep the pot dry; do not water. When the temperatures become warmer (early spring), watering can resume, new growth will emerge and normal routine care can continue.

Propagation of Caladium is done at the beginning of the growing season (early spring) by use of tubers.

How to propagate Caladium from tubers

Large Caladium tubers can be divided into several sections. Ensure each division has at least a node (growing point) from which new growth will sprout.

Bury the Caladium tubers sections about 1 in. deep with the growing point side up in moist, free-draining soil.

Ensure the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.

Place the set up in a warm place until growth emerges on your Caladium tuber section.

Allow the new Caladium plant to be well established before transplanting after which routine care can begin.
