Dragon Wing® Red Begonia and Angel Wing Begonias can be described as Wax Begonias on steroids. Leaves and flowers are bigger than their small cousins. Dragon Wing Begonia is a vigorous plant with abundant flowers all summer long. If grown with support, it will grow upwards but if left alone, will have a mounded shape, growing 12 to 18 inches high with equal width. Dragon Wing Begonia is a favourite for hanging baskets.Even when temperatures blaze, Dragon Wing keeps on pumping out the colour in gardens and planters all season long.
