|L. superbum is a vigorous, stem-rooting true species lily with rhizomatous bulbs, purplish green stems, and linear to lance-shaped leaves, mostly borne in dense whorls. Bears long racemes of up to 40 unscented, pendent flowers, with maroon spots, and green toward the bases. Prefers moist, acidic soil, and full sun or partial shade. Eastern US.
Deadhead spent flowers, but wait until stems and leaves turn yellow to cut back to within a few inches of the ground. Spring and fall are the best time to transplant, even though they can be transplanted any time. Provide ample moisture while flowering, but can take periods of drought otherwise.
