Monarda lambada

This very showy bee balm is reported to be resistant to mildew. It grows to 2-3 feet tall. The yellow flowers are surrounded by large bracts in shades of pink, purple, and lavender with white dots and bloom for a long time in late summer. A beautiful cut flower that attracts butterflies and bees. Pleasant mint-basil scent. Zones 5-9, but doesn't return reliably every year, so it's generally grown as an annual.
