Although greatly reliant on its training when still young, ‘Red Dragon’ in general remains at maturity loosely structured showing its appealing form. ‘Red Dragon’ will not grow true from its seeds & is propagated from cuttings & grafts. It needs rich soil, neutral to acidic, moist & well draining. Growth rate is slow, though young specimens develop more rapidly at six or eight inches per year & will at first require attentive training to develop the most artful form. After the tree is well trained & shaped during its youth, the slow rate of growth into maturity means it will retain its shape without constant attention. Over time the tree can become wider than tall, though it is trainable to retain a narrower form. As a semi-dwarf it is usually encountered in the three to five foot range (at the ten-year age), but seven or eight foot specimens are encountered & over a great length of time it will become even larger. Its finely dissected leaves are said to resemble dragon claws. These leaves are a gorgeous purple-red at emergence in April, darkening to a purple burgundy which it holds strongly throughout the Summer. The leaves turn bright-bright red in the Autumn. The bark of young limbs is purple to nearly black, quite striking in winter when leaves are gone. Wow!!
