People buy crotons here at the end of the summer when everything else is scorched and boiled. My experience is that if you're too nice to them, they die in a hurry. I used to try to keep them as houseplants and they never lived. I have one in a pot on the front porch but I'm pretty sure it froze last night. It's the same as the one on the bottom right in Lyn's picture. I love the colors but I've learned to think of them as an annual bedding/container plant. I planted pansies, snapdragons and petunias for the winter. They got the covers. I tried not to look the croton in the eye when I walked away from it.
Our Lowes never has plants on clearance either. If they do, they're about 95% dead and they still want 1/2 price for them. I used to find interesting houseplants at Home Depot but now they never have anything new. Just tons of pothos and corn plants.
