Need something architectural? Giant elecampane can help you with that. Colossal clumps of elephantine leaves send up 6-foot stalks in early summer topped by clusters of large flowers that resemble yellow spider chrysanthemums. Use it as an individual statement-making specimen, or in combination with finer-leaved perennials such as Amsonia hubrichtii.
Full to part sun; average to moist soil; 6'x3'; early summer; Zone 4
Propagated from seed; deep 3.5-inch pots
