I seem to be one of the only ones posting here that doesn't live in "croton country". I live in Delaware but I've managed to have a decent croton collection in pots. This is my back patio where most of my collection lives during the summer. I also grow other tropicals and sub-tropicals, like palms, citrus, bananas, etc. Here are my oldest crotons. The one on the left is a "Petra" I think, purchased at my local Acme in 1982. The one on the right is an "Andreanum" I think, which I got as a cutting from my aunt's house in Hollywood. Florida in 1969 when I was 11 years old! Here is the "Petra" up close. It's foliage is quite variable - if it is a "Petra" it's not like the perfect ones they seem to sell today. Here is the "Andreanum" up close. I will post more photos after this (I got a message that there's a 4 photo limit?!?!?).... please feel free to correct me if you think I have any of the cultivar names wrong!
