A few weeks ago, I planted 300 hundred caladiums in a giant (GIANT!) bed in the middle of my garden. It is difficult for me to capture the scale of this section and its location in a single photograph, but adding it has definitely helped me create a park-like feel to the gardens, as it essentially separates two very large areas into two distinct garden rooms.
The caladiums are starting to come up, and I imagine these are probably one-third to half the size they are going to be. (And there will be a lot more red ones in the mix… they were the last ones I planted.)
If you are interested in ordering caladiums, especially in bulk, I highly recommend the folks at Caladium World in the caladium capital of Florida, Lake Placid. (The town also has a Caladium Festival every July.)
