Most are bulbs or rhizomes rather than seeds. Angel Wings (aka Caladium) comes in many different color combos. Any of the many fern varieties. Hosta - lots of choices - as long as the soil mix is well draining but they won't work if the soil is constantly soggy.

So why is the soil "soggy" and can't it be improved?
