Paperbush (Edgeworthia) flowers hurt by early frost

Q: My paperbush (Edgeworthia) flowers were very small this year. I think the cause was the long, hot, dry summer at a time when they usually set their flowers for winter.

A: I think the problem was caused by cold, not drought. On November 11-12, 2019, temperatures dropped suddenly down to 25°. A couple of weeks afterward, a radio caller described the flowers on her paperbush as being crumbly and falling readily when touched. I saw the same thing on my own plant. As the weeks have passed, I have seen most of my flowers disappear. My guess is that our plants did not have enough time to acclimate to the sudden November cold and that caused the effects we are seeing now.
