Interpretive Summary: 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, 16-hour light + 8-hour dark, and 12-hour light + 12-hour dark. The results indicate that the treatment 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. Manipulation of photoperiod could potentially make blood lilies good candidates for commercial production in Florida as potted plants.

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.
