Plemonium caeruleum is the Latin name for a plant sometimes called Jacob's Ladder. I think the name ladder came from the way the foliage reminds us a little bit of a ladder with rungs, the plant is quite attractive and makes a nice additition to a bed of hostas or other shade loving plants. This North American native perennial plant is hardy from zones 4 to 8. It prefers a humusy, rich, evenly moist yet well drained soil; it also needs a shady to partially shaded location such as morning sun or dappled light all day. In bloom it is about a foot and a half or slightly taller, it blooms in the spring. The small flowers are blue.
