Caladiums are the one of the most colourful foliage species in the plant word. I actually call them the "Ugly Duckling" of the Plant World, as juvenile they look totally different to their matured form - Strap, Lotus to Diamond Heads and more. The colour and pattern on some hybrids are truly spectacular and amazing. Some Plant Lovers do shy away from them as they go dormant over winter in the colder regions, and by Spring they start to pop their heads to reveal something extraordinary.
