Also in Momma’s Wildflower Bed:
You can see an older planting of caladiums I purchased in bulk from a South Florida caladium farm at Home Ownership and Family Compounds.
Update: In the comments, a question was raised about digging up caladiums at the end of the growing season. I have never done this. Too lazy, I guess. I leave them in the ground and a scattering of them will return the next year. Knowing that only a few will return, I treat caladiums like annuals. I buy new, fresh bulbs (not those sold in plastic bags at big box chain stores) and find that the bulbs quickly grow into large plants, as you can see from those white/spotted caladiums above (which were bulbs purchased this year).
