Dendrobium hybrid "Uniwai Pearl" was developed by the University of Hawaii in the 1970's for the cut flower industry. Upon checking for the parentage of this Dendrobium, I found a website that has all of the University of Hawaii's cultivars (http://www.hfloral.com/Cutflower/UH/H0619.html). On this website I found out that "Uniwai Pearl" was the third seed-propagated Dendrobium released by the University of Hawaii. It is a cross between an inbred Jaquelyn Thomas UH44 strain and a tetraploid Neo Hawaii (Y972) that arose from meristem culture.
Blooming Time: The arching flower spikes yield up to 20 showy 3 inch (7.5 cm) flowers per flower spike from early summer through the fall.
Culture: Dendrobium hybrid "Uniwai Pearl" is an epiphytic orchid, which does best in a compost of pine bark. They require regular watering and fertilizer and need to be fed at least twice a month during the summer flowering period. We use a 30-10-10 fertilizer diluted to ½ the strength recommended on the label. In the fall, water should be reduced for the winter rest period and watering should be stopped in winter. For good flower formation they need to be kept between 48°-50° F (9°-10° C) in the winter months.
Propagation: Dendrobium hybrid "Uniwai Pearl" is propagated by division in the spring.
Dendrobium hybrid "Uniwai Pearl" was featured as Plant of the Week June 7-14, 2002.
