I have a raspberry patch that was started several years ago with plants from my dads house. They grow great, bear heavily, and have excellent midsummer fruit. when they're bearing you can get more than you can eat at once without ever moving your feet.

looking for suggestions on how I might identify the strain.

in central MN Zone 4 they bear starting around the 4th of July and last till about labor day. sweet with excellent flavor.

fruits are bright red and about the size of a dime or nickel. left too long they darken a bit and get loose and readily fall off. (they're still very good eating at this point.)

they grow like crazy. heavy watering increases fruiting significantly (found this out when I left the sprinkler running all night by accident.)

canes grow to about 5' high. I cut the 2 year olds and leave new growth for the following year. yield went up significantly after I learned how to prune the canes.

suggestions?

thx in advance for help.
