Continuation of update: 1st photo is Mammie (mammey?). This is planted along west road below an African Oil Palm. Got heavy wind of 33 degree F temperatures. Very little leaf drop. This common cultivar seems pretty hardy with my conditions. There is about 5 inches deep of mulch around this one. 2nd photo is Excellente. North part of property with a wood fence that blocked the wind. This plant gets some mornng sun then stays in the shade the rest of the day. Because of the shade, this croton survives in an area that does not warm up much. 3rd photo is Piecrust. This photo does not show it but this croton took a pretty good beating. North side of property and got blasted with the cold winds. Is in some pretty decent shade that did not warm up very well during the cold wave. This croton lost over 80% of its leaves. Was looking fabulous prior to the cold. 4th photo is Rudy Bachman. This guy got the crap beat out of it as well. It was absolutely gorgeous before the cold wave and was one of my favorites. It is planted next to the Piecrust and recieved the same conditions. Both have about 5 inches of mulch around the base to keep the roots warm. Hang in there Crotonheads, Spring is around the Corner!
