Growing Valerian in Zone 2A

Valerian is a tall, fragrant perennial grown for its roots, which are used in calming supplements. The flowers attract beneficial insects in droves.

Zone 2A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Grows to 4-5 feet tall — plant toward back of borders
• Flowers attract cats similarly to catnip — protect if needed
• Roots are harvested in fall of the second year for maximum potency
• Attracts earthworms to the surrounding soil — excellent for soil health
• Self-seeds freely; deadhead to control spread

Companion Planting

Good companions: most vegetables (beneficial insect attractor), lettuce, peas

Avoid planting near: Too-close planting where it will shade shorter crops

Harvest Timeline
