Summary
Monarda ‘Marshall’s Delight’ rated very poorly due to severe powdery mildew infections that caused significant damage and defoliation by midsummer. This performance was especially disappointing because ‘Marshall’s Delight’ was specifically selected for its superior disease resistance by a Canadian breeding program.
