Few plants capture the vibrant colors of a Florida summer quite like Caladiums. Caladiums are desirable for the vast variety of color combinations and height. They are great for ground cover, edging, and container plants. Their versatile nature makes them a hit in a multitude of landscapes.

WHAT DO THEY REQUIRE?
Caladiums thrive in zones 8-11. They can be grown from bare tubers or full leaf plants nearly year-round in these zones. Plant caladium tubers in soil that is at least 60-70°F. Cooler soil will result in tuber rot and slow growth. When planting tubers place them “eye side” up (the puckered, knobby side). Plant them 2 inches deep and 8 to 12 inches apart from each other. Caladiums prefer soil with high moisture and adequate drainage. Keeping soil moist but not soaked may require frequent watering.
One of the keys to growing healthy caladiums is selecting the proper planting site.
Most caladium varieties perform best in:
- Partial to full shade
- Well-drained soil rich in organic matter
- Consistently moist—but not waterlogged—conditions
While many traditional varieties prefer shade, newer sun-tolerant cultivars can handle several hours of direct morning or filtered afternoon sunlight. Be sure to read the plant label when selecting varieties for your landscape.
Fertilizing for Healthy Growth
Caladiums benefit from the light application of a balanced, slow-release fertilizer during the growing season. Avoid excessive fertilization, which can reduce leaf color intensity and encourage unnecessary growth.
Always follow fertilizer label directions and avoid applying fertilizer before heavy rainfall to reduce nutrient runoff into Florida’s waterways.
The University of Florida has developed a number of cultivars that thrive in our warm climate. Pink and multicolored caladiums include, ‘Passionista’, ‘Summer Pink’, ‘Tapestry’, and ‘Fiesta’. For red caladiums, try ‘Sizzle’, ‘Red Hot’, ‘Royal Flush’, and ‘Cherry Tart’. For white, seek out ‘Cosmic Delight’ and ‘Icicle’. Dozens more cultivars are available, and you can preview some of them in our article, Caladium Cultivars Developed at UF.
