As an avid collector of palms, I have many "understory" palms growing under canopy. Because of the "crowding" of these understory palms, I would like to add slow growing cultivars of crotons. The croton colors help to delinate and define the individual palms making them more apparent to the eye. It does not make sense to plant a fast growing cultivar that will require pruning as it competes for the filtered light with the palm. Adding slower growing cultivars would be the appropriate solution for these plants to becoming sybiotic. Please, everyone chime in here and list which cultivars you have experienced being slower growing. Best regards to all, Ron.
