Uses: Valerian is a traditional sleep aid and pain killer, as well as helping to calm nerves during stressful times. Also, valerian is not known to be habit-forming like many modern pharmaceutical medications for sleep and pain control. The roots are used medicinally and are typically dug up after at least two years of growth. They can be used fresh or dried in foods or tea.
Hardiness: USDA Zone 4.
Growing Tips: Valerian has tall, white flowers with a beautiful scent. They also make great cut flowers. Keeping your plants deadheaded will prevent them from spreading too much by seed. Valerian is also much-loved by dogs and cats, so you may want to put a barrier around small plants to protect them until they’re big enough to withstand your pets’ attention.
