I tired I planting Crotons in my garden only to have them drop leaves in the Winter. I now put them through a chill test. Any Crotons purchased in the warm months now must sit in their pots through the chilly months. To pass the test no leaf drop or very little (30% or less) and the plants are then planted in the garden. Here are the first two to go into the ground this year after passing the test with 0% leaf drop. BTW I have no names on these.
