Caladiums (Caladium ×hortulanum Birdsey, Araceae Juss.) are ornamental aroids valued for their bright colorful leaves. They are commonly used as container and landscape plants. Pink cultivars have been very popular and the most popular pink cultivars have been Carolyn Whorton, Fannie Munson, and White Queen (Bell et al., 1998; Deng et al., 2008). They ranked No.1, No.3, and No. 4 in acreage (or popularity) according to a 2003 survey of the caladium cultivars commercially grown in Florida, where more than 95% of the caladium tubers used in the world are produced (Bell et al., 1998; Deng et al., 2008). Developing new pink cultivars has been an important breeding objective for the University of Florida/Institute of Food and Agricultural Sciences caladium breeding program.
UF-172 is a fancy-leaved cultivar uniquely characterized with large attractive pink blotches and red petioles. It is intended for use in large containers and sunny landscapes. It has demonstrated high tuber yield potential and performed well in container forcing and landscape use. Its performance as a pot or landscape plant was significantly better than ‘Carolyn Whorton’, ‘Fannie Munson’, or ‘White Queen’. ‘UF-172’ also sprouts earlier than these existing commercial cultivars. These characteristics should benefit growers producing tubers, those marketing potted or bedding plants, and consumers and landscapers using caladiums.
