When grown in the shade, how tall will it get? I am ammending a shade bed
now with compost mixed into a silt/clay soil. How deep are it's roots? How
quickly will it spread? I am looking forward to drawing in the butterflies
with it, should it grow somewhat shorter in the shade than the 7 or 9 feet
that I understand is possible.
