Variegated Figwort.  One of the best variegated perennials.  This is a big and robust plant simply needing a rich moist spot to really strut its stuff in either sun or semi-shade.  Squinchy little brownish flowers are curious additions to a showboating 4' high plant.  This is easy but not so easy that you regret having it in the garden.

Yellow Figwort.  A plant of tough constitution with terminal heads of small yellow flowers which are quietly distinctive in that they resemble nothing else in your garden.  We got seeds of this from Senior Curator at Denver Botanic Gardens, Panayoti Kelaidis who grows this in his home garden.  Tolerant of some shade, some dry and some deer, this is easy.
