Northern California, CA (Zone 9a) | October 2006 | positive
Quoted from a friend Paul Tsamtsis of the Sacramento ABS branch.
"This begonia is classified as 'tuberous'. It's parentage...Read More is B. evansiana x B. 'Bhotan species'. B. evansiana (=B. grandis spp. evansia) comes from China.
This plant grows from a fairly large tuber. Being tuberous, it starts going dormant as the days grow shorter in the early fall. At this time it also starts exhibiting another characteristic of some tuberous species. That is that bulbils start forming in the leaf axils. They are nascent tubers that fall to the soil surface until early spring. They must remain uncovered to germinate in the spring.
It appears to be nearly as hardy as it's familiar parent."
(B. grandis spp. evansiana reportedly survives temps down to 19ºF or -7ºC.)
