This cultivar has always been a weak grower for me. Purchased two 5 ft tall plants some years ago. Great looker initially. However, almost every other winter they defoliated and with the past two ^%$#@! winters here, they went into rapid decline. The largest one got its final pruning today before the root system gets dug up. What little new growth that came back this year went into a fast wilt mode the past week. See attached pics. Note the exfoliated bark even at the base - about 1.5" diameter.
