Be on the lookout for a great new caladium variety from the University of Florida - 'Cranberry Star'. This new variety is ideal for use as a potted plant or accent or border plant in shady landscapes 'Cranberry Star' has bright white leaves with green veins, similar to the leaves of 'Candidum'. But, it also has numerous bright purple spots on its leaves. I think it's very pretty.
'Cranberry Star' is not available yet, but keep checking with your local nurseries and caladium suppliers. I look forward to trying it soon!
