Breeding Caladiums

Caladium Breeding-1Caladiums have been in cultivation in Europe since the late 1700’s. In the early 1860's, Louis van Houtte and Alfred Bleu of France pioneered caladium breeding. Soon after throughout the 1880's, Adolph Lietz of Brazil and C.J. Bause and Richard Hoffman of England advanced caladium breeding.

Adolph Lietz displayed many of his 400 plus varieties at the Chicago World’s Fair in 1893, which aroused tremendous interest from the general public and horticulturists in the United States.

At the beginning of the 20th century, Henry Caladium Breeding-2Nehrling and Theodore Mead—two of Florida’s pioneering horticulturists—began caladium breeding in the U.S.

Henry Nehrling once had more than 2,000 varieties, and some are still in commercial propagation today. Meade’s efforts were focused on new lance-leaved varieties. After Meade’s death, caladium breeding declined until Frank Joyner started a backyard breeding project, which ended in the late 1950’s.  

In 1976, UF/IFAS initiated a caladium breeding program at its Gulf Coast Research and Education Center in Bradenton, Florida. Since then, the program has been the only major organized breeding effort in the world. 

Dr. Gary Wilfret directed the breeding program Caladium Breeding-3from 1977 to 1999 and then Drs. Brent Harbaugh and Baldwin Miranda led it from 2000 to 2002. Since late 2002, Drs. Zhanao Deng and Brent Harbaugh have been directing the breeding program.  

The UF/IFAS program has released 13 cultivars so far, and researchers are testing many new selections with improved or novel characteristics for future release. 

Currently, our primary breeding objectives are to develop new varieties with better leaf colors, resistance to diseases and nematodes, and tolerance to cold.
