I know this is an old thread but I was looking for posts on Nanking Cherries. I'm worried about mine - the buds haven't swollen nor broken and here it is April in Georgia. I think they may not have made it through the winter, alas - yet the branches are still quite pliable when I see if they will bend or break. I suppose I'll wait and see but I rather did expect to see the buds swollen and breaking by now, what with the warm weather. Everything else I have potted up with it is leafing out and or flowered that were kept right along with them. I was wondering if these sometimes bloom really late but posts I am finding suggest they often bloom in or around March.
