Looking fabulous in the woodland garden as August gives way to September is the Chinese Begonia grandis ‘Alba’. We never have enough plants that will flower in the summer/fall woodland garden, so I can’t imagine a garden without cold hardy begonias. The sprays of white flowers and red backed leaves make B. grandis ‘Alba’ a great, easy-to-grow, and extremely winter hardy garden specimen. Hardiness is Zone 5a-9a.

So beautiful! Thank you for the continued inspiration!
I’m trying to determine if I can grow this plant where I live (Central New Jersey). I’ve successfully grown cane-like begonias in containers, keeping them on my shady porch during the summer and bringing them into my sun room for the winter. Tuberous begonias have been a complete failure for me. I consulted the American Begonia Society classification system and can’t find a type that matches these. I would appreciate any information you can provide. Thanks for your help. Maryann
This should be fine in the ground in Central NJ. It goes deciduous in winter and requires cold when dormant, so don’t bring it into a sun room for winter.
Is there an alba flower version of Begonia grandis ‘Soigné’ (with dark leaves)?
Not that we’re aware of.
