Understanding Caladium and its Varieties

Caladiums, which are tropical perennials with colorful heart-shaped leaves, originate from tropical forests in South and Central America and have their unique requirements outlined in the care guide for caladiums. Caladiums are known and grown for their large heart-shaped leaves that exhibit stunning color combinations of white, pink, red, and green, making them key garden plants. Though caladiums may bloom and produce a typical arum-type flower, most people practicing caladium care remove the inflorescence, as it takes energy away from the plant that could be used to grow more leaves or a bigger tuber.

Caladiums, typically grown as annuals in the growing guide, are planted outdoors in late spring once the soil warms. Caladiums make excellent plants for shady yards and gardens, but interestingly, most varieties are surprisingly tolerant of the sun. They are also popular as houseplants due to their ability to grow in the shade. As outlined in the caladium care guide, caladiums prefer soil that is well-drained, moist, and rich in nutrients.

There are two types of caladiums: “Fancy Leaf” and “Strap, Lance, and Dwarf” varieties. The “Fancy Leaf” caladiums have heart-shaped leaves with smooth flat edges and can grow anywhere from 12-36 inches tall. The “Strap, Lance, and Dwarf” varieties typically grow 6-18 inches tall and have heart-shaped leaves with a wavy-edged curly leaf.

Some of the best caladium varieties include ‘Pink Symphony’, ‘Iceberg’, ‘Carolyn Whorton’, and ‘Miss Muffet’. ‘Pink Symphony’ is a strap-leaf caladium with pink and white foliage and a dark green vein spreading throughout. ‘Iceberg’ is a strap-leaf variety with stunning green foliage mottled with cream and dark green. ‘Carolyn Whorton’ is a tuberous perennial with vivid pink leaves with a dark green pattern and red veining. ‘Miss Muffet’ is a strap-leaf or sun-tolerant variety that has foliage with season-long color and texture.

Caladiums are also known by other names such as the Heart of Jesus, Angel’s Wings, Elephant Ears, and Gabi-Gabi plant in the Philippines.
