Next year I might give them a try again. I kept the two you gave me about 5 years ago, took them through two winters planted outside. Then I puppy sitted for my daughter. Little Izzy dug both of them up. I replanted and she dug them up again. When I found the the second time the roots and all were all dried up. We had some very hot/dry weather.
I wonder if these two entries in the database are the same brug?
