I have never had this happen before! My Caladiums "Pink Symphony" emerged after planting with only the flowers - spathes - and no leaves yet! Isn't that a bit odd?? I've had them bloom before but usually after it's got a fair number of leaves. Oh, I do have ONE tuber with ONE leaf. I've got them in the shade and it's been extremely warm, so I know they should be happy. I just cannot figure out why no leaves yet!
