Opinion
"
The Nikko deutzia is a very appealing plant when in full flower, The large white racemes that literally engulf the plant are quite aesthetically pleasing. However the majority of the year the plant looks quite ratty and becomes unkempt over time so consistent renewal pruning is required to maintain a desirable form. All in all a nice plant when in bloom, nothing more.
