Begonia ‘Benitochiba’ is a really exotic looking rex cultivar. It is published that Isamu Misono, a noted Japanese hybridizer crossed Begonia ‘Filigree’ (a rex cultivar) with the Brazilian species B. luxurians and the offspring is ‘Benitochiba’, That being said, judging from the characteristics of this cultivar and chromeosome numbers of the species, many believe the species parent is B. hemsleyana. The compound leaf is a silver pink color with black or purple markings along the main veins. In cool temperatures and bright light the leaves are a bright metallic pink. It has an upright growth habit. The flowers are pink. This is really a choice rex begonia.
Shade to partial shade, temp. 50 to 95 degrees, 12 to 15in. tall, allow getting slightly dry between watering
