Non Stop Mocca Begonia is an exciting new hybrid of tuberous begonia with black foliage. White flowers against black? It doesn't get better than that. 
 
Commonly grown as a house plant, these begonias are perennials in zones 9-12. They can also be grown as annuals. 
 
Reached 12 inches tall and wide
 
The seeds are pelleted as they are naturally tiny. We sometimes send seeds off to be pelleted (coated with clay to preserve the shelf life of the seeds as well as aid in making them easier to see for planting.) 
 
This is for 20 seeds
