Hello; Thanks for submitting your garden and landscape questions to the University of Maryland Ask Extension Service.
Hyssop plants (Agastache) are easy plants to grow in a landscape as new plants can sprout from harvested seed, but they can sometimes be weak perennials and not return the next year.
You can transplant them this fall by first selecting a site for your transplants. Improve the soil by adding organics [shredded leaves or compost]. Cut back perennial old foliage to the ground, carefully dig the plant and its roots out of the ground and place plants in their new location. Add organic mulch [leaves, straw, pine-needles] over the soil to hold moisture, prevent weed seeds from sprouting and prevent soil heaving from frozen soil. See this UMd Extension webpage on care of perennial plants:

Good luck in your landscape. Christopher
