I have observed Amelanchier (Juneberry) rebloom in the wild; once in late
fall another time in early winter.
I attributed it to the unusual warm spell at the time. These trees (large
bush) were on a rock ridge where as other trees in the area on better ground
were not in bloom. Amelanchier normally blooms in early spring.
