One of my favorite locally owned greenhouse/nursery has tons of unnamed hydrangeas. One var. is beautiful, healthy, almost three feet tall and have huge pale pink mop-head blooms...the other hasn't bloomed yet but has var. leaves, they are about 2.5' tall. They are in 3gal pots.. Since he inherited them from the last owner, He is asking 10$ but he will let me have as many as I want for $5 each...

I love the pink ones and purchased 4 and I am thinking of going back for more and a few of the var. leaf ones also... IS this a good idea? He is growing them in part shade and they are doing well. Thank you for any suggestions/Ideas/thoughts..
