BEGONIAS -- ARE THEY AN ANNUAL?
We purchased a home recently, with begonias planted in window boxes. Lovely in August, but they're getting leggy with no new flowers over the last several weeks. Will they survive a Minnesota winter, or should I consider them an annual and pull them up once we have a hard frost? (We're in Rush City, temp early this morning was 28 deg.) Thanks very much!

Begonias are only perennial in tropical and subtropical zones. They can be overwintered as houseplants. If you are interested, there is more information see: http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=a562information
