smilacina racemosa

 A superb, native flowering plant that's technically a part of the lily family, False Soloman's Seal is a shade-loving, easy-to-care-for native perennial that features Lily-like foliage and large plumes of creamy white flowers that bloom in late spring and early summer. False Solomon's seal grows to about 3 feet wide and tall over time. It prefers moist soils, but can tolerate dryer conditions as well. Dappled sun would be its most preferred light conditions. Adding organic matter, like decaying leaves, to its soil would benefit it as well.

Naturally occurring in most of the midwest and mid Atlantic. Arrives to you in a gallon-sized pot.
