A few days ago I received the absolute LAST trees I can order...at least til I get my Christmas greenhouse!! One of them is a beautiful dwarf Cara Cara. It's lush & full but it has these huge [1 1/2 inch] semi-soft thorns, is this normal? I thought oranges didn't have thorns, at least not as humungus as these are. It's a 2-3 yr tree from Four Winds.
