Lemon verbena
Overview
A South American shrub with the most intensely lemony fragrance of any plant — far more concentrated than lemon itself. A single crushed leaf releases an intoxicating citrus aroma that lingers on the fingers. In mild climates it grows into an impressive shrub; in cold areas it makes an excellent container plant brought indoors for winter.
How to Grow Lemon verbena
Plant it in well-drained, moderately fertile, loamy soil, at a slightly acidic pH of 6–7.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Match it to the right spot, and the rest is mostly patience.
Companion Planting & Soil
Lemon verbena grows well alongside rosemary, lavender, and basil.

Planting Calendar
When to sow, transplant, and harvest by growing zone.
| Zone | Action | Months | Notes |
|---|---|---|---|
| Cold (1-2) | Start Indoors | Mar — Apr | Start from cuttings indoors; grow as annual or container plant — not frost hardy |
| Cold (1-2) | Transplant | Jun — Jun | Move outdoors after last frost; bring in before first fall frost |
| Cold (1-2) | Harvest | Jun — Sep | Harvest leaves anytime; strongest lemon scent of any herb; excellent dried |
| Cool (3-4) | Transplant | May — Jun | Transplant after frost; deciduous — drops leaves naturally in fall |
| Cool (3-4) | Harvest | Jun — Sep | Cut sprigs for tea, desserts, and potpourri |
| Moderate (5-7) | Transplant | Apr — May | Plant in spring; full sun; lean soil intensifies fragrance |
| Moderate (5-7) | Harvest | May — Oct | Harvest through growing season; dry leaves retain scent for years |
| Moderate (5-7) | Prune | Mar — Apr | Cut back by half in spring; new growth emerges from woody stems |
| Warm (8-9) | Transplant | Mar — Apr | Plant in spring; can become large shrub (6-8 ft) in mild climates |
| Warm (8-9) | Harvest | Apr — Nov | Long harvest season; strip leaves before fall leaf drop |
| Hot (10+) | Transplant | Feb — Mar | Plant in late winter; grows quickly; provide afternoon shade in desert heat |
| Hot (10+) | Harvest | Mar — Nov | Harvest from spring through fall |
Uses
In the Kitchen
In the kitchen, lemon verbena turns up in more than one form: herbal tea with intense lemon flavor; infused into cream, custard, and ice cream; chopped into fruit salads and cocktails.
Medicinal & Folk Use
In herbal and folk tradition, it has been valued in several ways: digestive and calming tea traditionally used after meals; antioxidant compounds support immune function; traditional South American remedy for fever and congestion. These are traditional uses, not medical advice.
Beyond the Garden
Lemon verbena earns its keep past the plate, too: intensely aromatic container plant for patios; dried leaves retain scent for months in sachets.
