No ID from me but I grew Tuberous Begonias for many years. The best tubers, in my opinion were developed on the west coast in Capitola, California. When I was buying tubers I always chose the American type hybrids....they had larger, fuller blossoms in more exciting colors. The pendula were the older hanging type. Those called Hanging Basket were again developed in California and featured the larger, fuller flowers which bloomed heavily. If memory serves me right one of the first American hybridizer was named Brown. Vetterle and Rienalt [sp?] and Antonelli's were the top California breeders and growers. I had the opportunity to visit both nurseries several times but they are both gone now. To bad. I think the earlier ones were called Belgian Bulbs.
