From September 2017 through February 2018, this open field research was conducted with 6 random treatments and 10 replications. Plants grown under sunlight source with paclobutrazol (PBZ) treatments were compared to those grown under sunlight plus 2 h night break (without PBZ) (control 1) and those grown under sunlight source (without PBZ) (control 2). The results showed that PBZ treatments lowered both height and peduncle length substantially. In comparison to control 1, the 600 mg/L PBZ treatment led in non-significant changes in physical growth and anthocyanin content in coma bract and fertile bract. Plants grown under sunshine + 2 h night break without PBZ had the shortest number of days to inflorescence appearance (day 46) and first flower opening (day 72). Plants cultivated under control 2 conditions had the largest delay in inflorescence emergence (day 61) and first flower opening (day 92). These findings will aid in the low-cost cultivation of C. alismatifolia cultivated in the open field during the off-season.
