Mildew-resistant Monarda

(Asked on "Perennials" forum, but this should be a good question for regional forum also)

I am looking for recommendations on mildew (and other disease) resistant monarda cultivars. I grew three varieties starting last summer: "Mahagony", "Bluestocking", and the species M. fistulosa. Mahagony succumbed to root rot or some related blight. Bluestocking came up but is heavily mildewed and the flowers don't look too attractive (because of poor plant health). M. fistulosa (species) did the best, and flowered heavily, but has required extensive staking because of the tendency of the tall, thin stems to flop over. I think my soil is average, medium to moist silt loam, and the location gets partial sun (maybe 4 hours per day).
