Begonia Maculata Double Dot, Double Dot, Cane Begonia: This Cane Begonia nearly doubles the number of silvery white foliage dots that made the Polka Dot Begonia so popular. Leaves in the shape of angel wings are deep green and decorated with these very prominent dots. Leaf undersides are green, sometimes with a slightly rosy blush to them. Simple pink florets rise up above the leaves at certain times in the year. With a more compact growth habit than the Polka Dot Begonia, this plant displays its best feature (its foliage) very nicely.
