Rudbeckia maxima has huge powder blue leaves (hence the common name 'Dumbo Ears') topped by yellow cone flowers in June and July.  The flower stalks rise to over 7' tall.   Rudbeckia maxima prefers moist, fertile soils but will thrive in average garden conditions in full sun.  It likes wet feet, yet is surprisingly drought tolerant.  Foliage is striking and almost tropical looking, like a blue-green Canna.  Seeds are an important winter bird food source.
