All three of these plants were grown from cuttings from the same limb of the mother plant (East Boca between Glades and Palmetto, there's a great collection of hard to find Crotons in that neighborhood.) They all looked exactly alike while they were in 3-gallon cans. The top one is in very heavy sun most of the day. The middle one is next to the waterfall and gets almost no sun at all. The last one gets sun for around 2 hours at midday. Note the red margin and red to pink midvein.
