CALADIUMS AS CUT FOLIAGE FOR FLORAL ARRANGEMENTS

Because of their ethylene sensitivity, something like Silver Thiosulfate should be considered in the holding water solution.  DO NOT PUT CALADIUMS IN A COOLER AT TEMPERATURES LOWER THAN 65°F (19°C). They are quite happy at room temperatures (75°-78°F: 23°-25°C). We have found that the petiole or stem can at times be weak and cause problems with the shelf life of cut caladium leaves.  This has been overcome by sliding the entire stem into a plastic soda straw similar to what is done for Gerbera Daisies.  Utilizing this method we have found leaves will last three to four weeks in tap water (though deionized water may work better).  Cut leaves just above where the stem begins cupping just above the soil line.  Smaller leaves tend to work better in a mixed arrangement than large ones.  De-eying the bulb before planting can enhance the number of smaller leaves. Do not cut leaves before they are fully opened. Recently matured leaves work best.

The cut leaves of the following varieties have shown promise:
