Last year I was able to hand pollinate some of my caladiums and actually got seeds! I potted them up and they germinated. You can see the thread about them here:
The thread "Caladium Seeds!" in
Tropicals forum
Over the Winter months they started withering away one by one until all I had left was one lone seedling. It finally succumbed in July.
So once again I hand pollinated some Caladium flowers and got seeds. I consider the first time around as a dress rehearsal of sorts and am doing things differently - first starting them in fine vermiculite. I'll be separating them in about two months and potting them up in a finer potting mix that what I used last time.
Hopefully I'll be able to keep at least some of these guys going to maturity.
