Variegated Solomon's Seal is a hardy shade perennial that thrives in and out of the ground... it lasts a long time in water, & it tolerates dry soil once established, and sprouts dainty white dangling flowers in spring. ~Norfolk Botanical Garden
Remember Hugulkultur in creating raised beds. Since I like the higher beds, filling the bottom half with prunings and such will reduce amount of topsoil needed to fill bed.
