I have a Tango Hummingbird Mint (photo #1) (Agastache Aurantiaca-Hyb.) Common name: Anise Hyssop. I had planted it in a large planter when I purchased it. Now I want to plant it in the ground. Is now a good time or should I wait till Spring, since that is the time of the year when I received it?
Photo #2 is my Dark Dragon Rose and I did the same with it. When should I transplant it in the garden? Now or Spring?
