This southern species is extremely rare in cultivation and no living specimens have been traced in the northern hemisphere, although it is established in New Zealand. Specimens planted at Wakehurst Place and at Tregrehan did not survive for long. It has been described as a very ornamental tree for a sheltered position, and praised for its attractive pink and red-tinted new growth (Hudson 2004). The Wakehurst plant was cut to the ground each winter, however, and was removed to make way for something more rewarding (Kew records).
