I have 2 Blue Velvet Hypericum schrubs in my backyard that are planted too close together. I don't know much about this schrub, such as when and if I can prune and how to propagate and even transplant one of the schrubs. I live in zone 3 - 4 and the plant seems to thrive here in Minnesota. It's a good 3 years old.
Thaak you in advance for your help.
