Does anyone have advice on growing this plant? I have it in zone 7b, morning sun, afternoon shade, amended clay soil, regularly watered, good drainage, but it simply won't grow. I planted three of them grouped together two years ago, and they are barely hanging on. If anyone has suggestions, I would be most appreciative.

Jacob's Ladder is a beautiful plant for the semi shaded garden that has pink tinted green and white foliage in the spring, is covered with masses of sky blue flowers in early summer, and then keeps its variegation all season long. It prefers moist, but well drained humus-rich soil, with some shade from the heat of the day.

This plant has been growing beautifuly in full sun in my zone 4 garden for 3 years now. . I bought 3 more this year. It spreads at a medium rate.. The foilage is just so beautiful. I just bought "'stairway to heaven" so I haven,t wintered it yet. I also have "snow and Sapphires" It dosen't set seeds for me but I have divided the rootball 4 times in 5 years. I think Jacob,s Ladders are one of my favourite plants.
