You'll thrill to the months-long production of colourful, gorgeously formed blooms. They thrive in problem shaded areas, so you can confidently plant them beneath trees or along fence lines. These begonias also make a great addition to any porch or covered patio. The fragrant blooms can be so numerous, they nearly conceal the fleshy, serrated-edge leaves. Covers 10-12 sq ft when planted together.
