Oh, Bill of Caladium bulbs for less..he sells bulbs and is an ATP member, he was the source donor of our raffle, that is why I got mine in the first place.
I started mine in April, had to wait, and even then, it took its sweet time to show up, almost June already. It seems to like part shade to full shade. I was even putting the container while it has no leaves showing yet in some full sun to help warm up the soil, to warm up the bulbs below. I notice the ones with more white color can tolerate the sun and heat better, the more colorful and with more green ones, like to be in shade. But you really have to water them everyday here once the leaves are showing up, they love our heat and very thirsty, otherwise the leaf stalks will easily flop. My garden gets so shaded by the city trees here in the afternoon, so it gets some good heat protection. I have a very short window of full sun. My other issue here is the winds..position them where there is not much crosswinds, it will tatter the wide leaves easily.
