Plant Patent #17,934.Like so many good things in life, 'Citronelle' was a complete accident -- a mutation on the lovely orange-russet toned 'Caramel'. But far from echoing its parent's warm tones, these large, rounded, lobed leaves are neon-bright and a blinding shade of chartreuse! Topped by small creamy-white bells in mid- to late-summer, they are showy season after season on compact plants. Plant 'Citronelle' with its cousins for an amazing display of foliage color!
