Technical Abstract: We evaluated the response of blood lily bulbs (Scadoxus multiflorus) grown in containers to three photoperiod treatments, consisting of 8-hour light + 16-hour dark (T1), 16-hour light + 8-hour dark (T2), and 12-hour light + 12-hour dark (T3). The results indicate that the second treatment (T2), consisting of 16 hours of light and 8 hours of dark provided plants with the best flowering uniformity and synchrony, although they did not differ from the control. Overall T2 could have a positive effect on blood lily flowering uniformity and synchrony. Manipulation of photoperiod could potentially make blood lilies good candidates for commercial production in Florida as potted plants.
