What Is Lavender?
Lavender plants, belonging to the Lavandula genus and the mint family Lamiaceae, boast an impressive array of 50 species and numerous cultivars. Native to mountainous regions and rocky slopes in the Mediterranean basin, including northern Africa, southern Europe, and the Levant, these shrubby perennials thrive in their natural habitat. In gardens, popular varieties grow up to three feet tall, reaching maturity within three years.
Characterized by narrow, needle-like or lightly toothed foliage in cool, silvery shades of green, they produce upright spikes bearing whorls of flowers, often accompanied by small flag-like bracts at the tip. A kaleidoscope of colors includes deep blues, mauves, blush pinks, purples, and whites. Aromatic leaves and flowers are rich in essential oils, emitting a sweetly herbal fragrance that’s a hallmark of lavender. For home gardeners, several species are commonly cultivated, including L.
angustifolia, the English lavender, which blooms from late spring to midsummer and excels in low-humidity climates. Its fragrant flowers come in shades of mauve, pink, purple, and white. L. dentata, or French lavender, boasts charming flag-tipped inflorescences in mauve and purple hues that flower in mid-to-late summer. With a deep, camphor-tinged fragrance, it thrives in hot and humid climates but requires protection from hard frosts. L.
stoechas, the Spanish species, features distinctive pineapple-shaped flowers in rosy pink, magenta, and royal purple shades. These plants are lightly fragrant with notes of eucalyptus, blooming in late spring with a lighter midsummer rebloom if deadheaded. Frost-tender, they’re hardy only in Zones 8 to 11 and most tolerant of heat and humidity. L. x intermedia hybrids, known as lavandins, are a cross between L. angustifolia and L. latifolia.
These highly fragrant plants produce long-stemmed flowers in shades of royal blue, mauve, purple, and white that bloom in midsummer. Fast-growing and forming large mounds, they retain their good looks over winter and offer improved disease resistance, performing well in humid settings and being cold-tolerant. Lavandins are typically hardy in Zones 5 to 10, with cultivars like ‘Phenomenal’ that can tolerate Zone 4.
Lavenders are known for their tough and durable nature, displaying good drought resistance when established. Requiring minimal fertilizer, they thrive in a variety of soils and need little care or attention aside from annual pruning and winter mulching.
Cultivation and History
Lavender has been a versatile and valuable plant across various cultures and timelines. Its uses extend far beyond its ornamental beauty, with a rich history in culinary, medicinal, and perfumery applications. In the Bible, lavender is mentioned in both Old and New Testament texts, including the Song of Solomon and Gospel of John. The ancient Greeks, Egyptians, Persians, and Romans employed it as a disinfectant, flavoring, medicine, and perfume.
Its introduction to Britain likely stems from Roman soldiers who used it in their baths and for its healing properties. The name ‘lavender’ originates from the Latin word ‘lavare,’ meaning ‘to wash.’ This herb played a crucial role during the Black Plague, where bundles were burnt for purifying smoke, while European physicians applied its essential oils to gloves and masks to ward off infection. As European settlers arrived in North America, lavender continued to flourish.
Today, it remains a staple in aromatherapy and alternative medicine, touted for its numerous purported health benefits, including anti-inflammatory, antimicrobial, antiviral properties, as well as treating disorders like anxiety, digestive issues, and insomnia.
Propagation
To propagate lavender, you have two options: sowing seeds or rooting stem cuttings. Starting with seeds, begin by sowing them indoors eight to 10 weeks before the last frost date for your region. Fill a flat with a moist, sterilized starter soil and sow the seeds over the surface, covering them lightly with about an eighth of an inch of soil. Next, place the flats under grow lights or in a sunny window covered with a greenhouse dome.
Once the seedlings reach three to four inches tall, transplant them into individual pots that are four to six inches deep. Before moving the plants outside, make sure all danger of frost has passed and overnight temperatures have consistently risen above 50°F. Hardening off the plants for a week by gradually increasing their exposure to outdoor conditions will prepare them for transplantation into larger containers or garden beds.
Seeds typically take between 14 to 21 days to germinate at temperatures ranging from 65 to 70°F, but they can take up to 90 days. If you’re looking to encourage germination, consider using a heat mat and grow lights. For stem cuttings, use hardwood stems that can be taken at any time during the spring or autumn seasons. For more information on this propagation method, refer to our guide on growing lavender from cuttings.
How to Grow
Lavender thrives in well-draining soil with a neutral to slightly alkaline pH, between 6.5 and 8.0, and full sun. When planting, ensure the soil temperature has reached above 50°F, or plant larger specimens in fall for added cold hardiness. The plants perform better in enriched soil, but can adapt to lean soils as well. To prepare the site, mix in aged compost, well-rotted manure, landscape sand, and bone meal for optimal root growth.
If your soil is acidic, add one-half cup of garden lime to balance the pH. Plant the lavender at a depth just below the crown, spaced 12 to 18 inches apart, and water gently after firming the soil around the roots. Mulch with pea gravel, keeping it one to two inches away from the stems to prevent root rot. Water regularly until established, then reduce frequency as the plants mature.
For an abundance of flowers, deeply water every two to three weeks until bud set, and weekly thereafter until harvest. Lavender also excels in containers, requiring adequate drainage holes and a well-draining soil mix. Fill containers with the same mix, planting at the same depth, and place them in full sun, watering when the top inch of soil feels dry.
Growing Tips
To achieve vibrant growth and an abundance of blooms, consider the following low-maintenance tips. Lavender requires well-draining soil and can’t tolerate standing water or excessive moisture. To improve drainage, incorporate landscape sand or pea gravel into the planting site. In regions with intense heat and humidity, select varieties like French lavender (L. dentata), Spanish lavender (L. stoechas), or lavandin hybrids that are better suited for these conditions.
When winter protection is necessary due to cold temperatures, choose a porous mulch material like pea gravel that won’t trap excess moisture. Pruning plants annually after flowering helps maintain a neat appearance and prevents leggy stems from forming. For the most potent fragrance, it’s essential to avoid over-fertilizing and over-watering your lavender plants. Additionally, knowing when and how to harvest flowers is crucial if you plan to use your lavender for purposes beyond the garden.
Harvesting
When it comes to harnessing the essence of herbs, timing is everything. For optimal results, collect the flowers when their essential oils are at their most concentrated. This usually occurs when about half the blooms on the stem have opened up, and the morning dew has had time to evaporate. Avoid harvesting during hot sunlight hours, as this can cause the oils to dissipate. Instead, snip off the stems just above the foliage using clean, sterile scissors or garden shears.
Bundle the stems together and secure with an elastic band or twine. Next, hang them in a cool, dark space with good airflow, allowing the flowers to dry out over the course of three to four weeks. Once fully dry, simply shake or strip the flowers from their stems and store them in an airtight glass jar.
Pruning and Maintenance
Pruning is essential for maintaining the health and appearance of lavender plants. It’s crucial to prune at the right time, as this process can stimulate new growth, promote a dense, mounded shape, and even encourage more oil production. The timing of pruning depends on your location and winter weather conditions. In regions with mild winters, pruning can be done after flowering or in autumn, reducing plants by around one-third.
However, if you live in an area with harsh winters, it’s best to prune in late winter just as new growth starts to emerge, rather than risking damage from frost. Pruning lightly after flowering is also a good option if you don’t want to harvest the flowers. For mature lavender plants with woody stems, pruning can be done throughout the growing season to promote more foliage and encourage a bushy shape. Our guide on how to prune lavender provides detailed advice on rejuvenating overgrown plants.
When it comes to fertilizing your lavender, remember that they don’t require much. Top-dressing in early spring with a two-inch layer of compost or aged manure is sufficient for garden plants. Container plants, however, can benefit from an application of a balanced 10-10-10 fertilizer after flowering. To protect your lavender during the winter months, provide them with mulch and cover if necessary.
A two- to four-inch layer of pea gravel can be used as mulch to protect roots from freezing temperatures. If you live in very cold conditions or experience drying winter winds, consider using burlap, floating row covers, pine boughs, or straw to add an extra layer of protection. For container plants, move them into a sheltered spot and cover if necessary. In extremely cold conditions, bring containers into an unheated garage or shed, but be sure not to allow the soil to dry out completely.
During the winter months, lavender plants are dormant but still require occasional watering to stay viable. If you prefer to bring your containers indoors during the winter, place them in a cool room with temperatures between 45 and 60°F. Ensure they receive bright, indirect light and water sparingly, as growth will be minimal while they’re dormant. Once warmer temperatures return, move the containers back outdoors.

Managing Pests and Disease
While lavender is generally easy to cultivate and hardy, there are some potential issues to be aware of. One common problem is the presence of aphids, which can collect on stems and while not typically fatal, may spread mosaic virus, a condition that can be deadly. To address this issue, simply use a strong spray of water from your garden hose to remove them.
Another unwanted visitor to lavender plants are spittlebugs, which may not cause significant damage but can still detract from the plant’s appearance. A good blast of water from the hose should be enough to get rid of these pests. Whiteflies are another type of sapsucker that can be problematic for lavender. While extensive damage is rare, they can still be a nuisance and difficult to eradicate.
To control whitefly populations, consider using natural methods such as encouraging ladybugs or releasing them in your garden, or spraying neem oil on the affected plants. It’s also important to be aware of two types of virus that can affect lavender: alfalfa mosaic virus, which is spread by insects like aphids and causes yellow, curled leaves; and root and crown rot, which can cause plant collapse. Infected plants will need to be removed and destroyed to prevent the spread of these diseases.
To avoid root and crown rot, make sure not to overwater your lavender, plant it in a location that receives full sun, ensure good air circulation around the plants, and keep organic mulches away from the stem and crown area.
