Funoh Kwon and Richard A. Criley

Bright red bracts with white flowers are produced by H. angusta from Sept through Dec in Hawaii. The inflorescences are valued as cut-flowers and the species is potentially adaptable as a seasonal potted plant. Sakai et al (1990) reported the LD responsiveness of this species, but-additional detail was necessary to permit scheduling. EK's PhD thesis developed a model for flowering in which the minimum day length requirement to initiate was 13 hr for 7 wk with another 15-16 wk required for development irrespective of the day length (12-18 hr) or temperature (14-22C). As with other phozoperiodically sensitive heliconias, 3 unfurled leaves were required to respond to LD. A growing degree model was developed to determine the time necessary to reach the 3-leaf stage. A 30-year temperature record was used to estimate the latest shoot emergence date that would permit initiation, development, and flowering under Honolulu conditions. The model was validated by comparison with commercial production records. Sakai et al. 1990. Bul Heliconia Soc Intl 4(4):10-11
