A very sort after*, rare superb small. fairly fast growing, shrub thats native to South America in mainly Brazil and Argentina. Enjoys full sun with a well draining fertile soil. Hardiness is a little sketchy, some information i can find suggest it could be hardy down to -12.2C, i would say definitely hardy down to -5C, will go deciduous in winter, harder frosts be cautious about with possibly fleecing.
