:) it's great for that - i know you both have an affinity with this plant! it is perennial plant, but you can harvest it in its 2nd fall season (or let it keep growing, but the root will lose potency). We divided the root ball, took some for medicine and replanted around a dozen small valerian plants the mother root had grown. It will also self seed and sow hundreds of plants into our gardens. We'll see how many plants come up next year :) I'm sure in years to come there will be an abundance of valerian tincture to share! That's the plan <3
