Lemon verbena is frost-sensitive and may require extra care to flourish every year. The best planting time is in spring since it requires some sun and moisture. Lemon verbena can be propagated either through their seeds or vegetative cutting.

Lemon verbena can grow through seeds that you can find in some online or local herb stores. Growing them in a colder environment can be a challenge, but will still work. If you should grow lemon verbena from seeds, sow them several weeks before the last frost. When confined to a container, lemon verbena may not bear flowers at all.
Start the lemon verbena seeds in a tray with a good garden soil mix of peat moss or compost. Sow the seeds at least an inch apart over the surface and cover them slightly with soil. Moisten the soil daily until the seeds germinate for at least 20 days. The germination can take longer depending on the conduciveness of its environment.
Transplant the lemon verbena in a large pot with at least a 12-inch diameter and ample drainage holes. You may opt to add pebbles to the bottom layer of the pot before adding loosely packed organic soil. Water the plant regularly, but do not let it run soggy. Keep the pot indoors in winter and water them once a week.
Alternatively, you can directly sow lemon verbena seeds in the garden if you live in a warm tropical climate.
Growing Lemon Verbena from Cuttings
If you want to propagate an existing lemon verbena plant, obtain a stem cutting with a leaf node in late spring. Plant it in a sterile, potting mix about an inch deep. You may use a rooting hormone for it though it is not really necessary.
Moisten the soil and provide humidity by placing the pot in a large plastic bag with a closed bottom. Tie the open end and allow about an inch of opening for moisture to escape. Mist the cutting if they feel dry and keep the soil slightly moist all the time.
You can check for the roots by gently tugging the plant to feel for any resistance. If it does, the plant has already developed. Remove the plastic bag and continue growing it for about two weeks before transferring it to a permanent container.
