General description
https://en.wikipedia.org/wiki/Begonia_grandis
The flowers are pink or white, borne in fall. As the common name "hardy begonia" implies, it is one of the hardiest species or cultivars of begonias.
It can hibernate well in hardiness zone 9a in southwestern Japan as bulbs or bulbils (bulbils are formed in axils). Other parts of the plant eventually wither to death as temperature lowers. However, it is generally regarded as hardy to zones 6-7. [1] [2]
