Lemon Verbena Seeds for Planting – A Complete Guide

Lemon verbena is a delightful herb admired for its refreshing citrus fragrance and flavor. While typically grown from nursery transplants some gardeners prefer starting lemon verbena from seeds. Growing lemon verbena from seed can be rewarding but requires patience and proper care. In this comprehensive guide, we’ll explore everything you need to know about lemon verbena seeds for planting.

About Lemon Verbena Seeds

Lemon verbena (Aloysia citrodora) is a tender perennial herb that thrives in zones 8-10. It can be grown as an annual in colder zones. The plant produces tiny white flower clusters that give way to minuscule brown seeds.

When starting lemon verbena from seed, it’s essential to source high-quality, heirloom seeds from a reputable supplier. Look for organic, non-GMO seeds with detailed origin and harvest information.

Lemon verbena seeds have a short viability period. For best germination rates, plant seeds the same season they are harvested. Storing seeds in the refrigerator can prolong viability for up to 1 year.

Seed Starting Tips

Lemon verbena seeds require light and warm temperatures to germinate. Follow these tips for success:

• Start seeds indoors 8-10 weeks before your last expected frost date. Lemon verbena seedlings need time to grow before being moved outside.

• Use a seed starting mix in cell packs or flats This provides fluffy, lightweight soil for delicate seeds

• Warm the soil to at least 70°F before sowing. Bottom heat speeds germination.

• Plant shallowly, no more than 1⁄4 inch deep. Gently firm soil over seeds.

• Cover trays with plastic domes to retain moisture. Remove domes after seeds sprout.

• Provide bright light 14-16 hours per day with grow lights or a sunny window.

• Maintain even moisture in the top 1⁄2 inch of soil. Avoid excessive drying out.

• Germination takes 14-21 days at optimal temperatures of 70-75°F.

Seedling Care

Once sprouted, lemon verbena requires attentive care:

• Thin seedlings to the strongest plant per cell when leaves emerge.

• Transplant promptly when seedlings have 2-3 sets of true leaves.

• Harden off gradually before moving plants outside.

• Plant in well-draining soil amended with compost. Provide partial shade.

• Don’t overfeed seedlings but do water consistently, allowing soil to dry out moderately between waterings.

When to Harvest Seeds

If you wish to collect seeds from your lemon verbena plants, wait until:

• Plants are at least 2 years old and well-established.

• Flower heads turn brown and dry out completely on stems.

• Seeds appear dark tan/brown and easily release from pods.

• Stems bearing seeds are clipped and moved indoors to finish drying.

• Seeds are cleaned from stems by hand and stored in envelopes in a cool, dark place.

Once your lemon verbena plants are happily growing, you can enjoy the aromatic leaves. Popular uses include:

• Adding freshly chopped leaves to salad dressings, marinades, and beverages.
