The 'Nonstop Mocca' series of tuberous begonias are all about drama and flamboyance. Tuberous begonias are inarguably lush, gorgeous specimens for the shade garden, but add in those dark green to almost black leaves as a backdrop for the vibrantly colored blooms, and people will stop dead in their tracks. Eight to twelve inches tall and about a foot wide, this upright begonia can be the centerpiece in hanging baskets, container planters, and garden borders. They do need some sun in order to produce the most blooms, but give them shade during the hottest time of the day. Water and fertilize regularly throughout the growing season to maintain Nonstop Mocca begonias' best looks right up until freeze.
