Abstract
The new and distinct cultivar of ornamental cultivar of hybrid ornamental bee balm named Monarda ‘Leading Lady Lilac’ has slightly-glossy, powdery mildew-tolerant foliage, flower heads of light lilac-purple flowers with lower petals accented by dark red-purple spotting, each head subtended by red-purple bracts. Flowering begins two weeks earlier than Monarda didyma cultivars and extends with fresh appearance over a long period due to lateral flower branches that develop above the terminal branches. The plant is short, compact and winter-hardy.
