I am a novice when it comes to Crotons and need some info. I have a few that I have planted in the garden in many locations. I have been inspired by the pictures I have seen here. I want to start a collection of Crotons in one general area of my yard. The Croton that is in that area has done well over the years. Now here is my novice questions: How can I know how tall a named Croton will get? All about the same? Larger the leaf the taller the plant? Small thin leafs shorter the plant? Is it hit or miss or a general rule of thumb? I want to do it right the first time. Here is a picture of the area I want to start the collection after removing all the Iris out of it.
