This stately tree is fast-growing and will be one of your favorites. She will grow to fifteen feet by the end of the third year! Her reddish pink flowers will add lovely color, her spreading habit and dainty leaves will give you a tropical feel. Makes strong, hard, dark wood that will grow with interesting curves and its branches make excellent bamboo stake substitutes. Not only do they make for some nice bonsai, but they have superior tree-house/climbing potential.
Cut back hard in the fall to keep it short and stocky. Excellent sustainability.
