Hi pvan42.
Thank you for your question.
It would be best to check with your local Home Depot Garden Department to see if that Begonia is available in white. This is a common color that is carried by The Home Depot. It may be available in our handy 8 packs. Although the plants are smaller, the value is great!
There is a larger Odorata White Begonia that you can get online, that is not available in our stores:

Please let us know if we can be of further assistance.
