Virtues: We love Rhus trilobata ‘Autumn Amber’ for its lustrous, aromatic deep green foliage that changes into radiant shades of amber, yellow, orange and red in fall. In spring before the new leaves emerge, bundles of tiny yellow-green flowers bloom. Small, rounded red fruits that persist until winter. It’s an interesting woody groundcover.
