Growing Lemon Verbena in Zone 3B

Lemon verbena has the most intense, true lemon fragrance of any herb — a single crushed leaf fills a room. It’s tender but worth growing every year.

Zone 3B has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Tender perennial — bring indoors before first frost
• Drops leaves when stressed or moved indoors; keep evenly moist
• Prune hard in late winter to encourage vigorous new growth
• Leaves hold their fragrance when dried better than almost any herb
• Infuse into simple syrups, teas, and cocktails for bright lemon flavor

Companion Planting

Good companions: other tender herbs, containers near seating areas

Avoid planting near: Cold drafts and frost

Harvest Timeline
