Planting, Growing, and Caring for Lavender Flowers

Catherine Boeckmann

Lavender adds aroma and soft beauty to the garden鈥攑lus, this herb attracts beautiful pollinators! Learn how to plant, grow, and harvest lavender. We’ll also discuss which varieties are edible and how to propagate lavender.

About Lavender Plants

The commonly cultivated lavender is the common or English lavender Lavandula angustifolia (formerly L. officinalis), which is hardy to USDA Zone 5. A bushy perennial, lavender grows from 1 to 3 feet tall, bearing small blue-violet flowers on spikes with blue-green, needle-like foliage. The oils in the flowers give the herb its distinctive balsam-like fragrance.

Called 鈥淓nglish鈥 lavender because it proliferates in the English climate, this plant’s main requirements are lots of sun and good drainage. It is not fussy about soil, and its presence lures bees, butterflies, and pollinators to the garden. Plant lavender along a walkway or near a seating area.

Interestingly, the name lavender comes from the Latin root lavare, which means 鈥渢o wash.鈥 Lavender was used in baths to purify the body and spirit, and today, it’s often used in soaps and shampoos. 

In addition, lavender has proven medicinal uses. When the essential oils are inhaled, lavender has calming properties that reduce anxiety; it’s also a gentle sedative for insomnia. In ancient times, lavender flowers were sewn into sachets to aid with sleeplessness. 

Lavender is even useful in the kitchen in baking and in drink recipes! Learn more below.

Planting

As mentioned above, lavender thrives in most soil qualities, from poor to moderately fertile. Lavender makes only one demand for the soil: It must drain well. Standing water and wet areas could encourage root rot. Amend compacted or clay soil with compost or aged manure to improve drainage. Plant lavender in a spot with at least 6 to 8 hours of sunlight each day (鈥渇ull sun鈥). 

When to Plant Lavender

  • Lavender is best planted as a young plant starting in the spring after the soil has warmed up to at least 60掳F (15掳C) and the threat of frost has passed.
  • If planting in the fall, choose larger, more established plants to ensure their survival through the winter.

How to Plant Lavender

  • Lavender is challenging to grow from seed; we recommend purchasing small starter plants from a garden nursery or taking a softwood cutting from an existing plant. Seeds may take up to 3 months to germinate, and seedlings must be overwintered indoors in cool climates. 
  • Plant lavender 2 to 3 feet apart. Plants typically reach between 1 and 3 feet in height.
  • Add mulch (rock or pea gravel work particularly well) to keep weeds minimal. Keep the mulch away from the crown of the lavender plant, however, to prevent excess moisture and root rot.

Growing

How to Care for Lavender

  • Water once or twice a week after planting until plants are established. Water mature plants every 2 to 3 weeks until buds form, then once or twice weekly until harvest. (Yellowing leaves are often a sign of overwatering.)
  • In colder growing areas, plants may need extra winter protection. Cover the plants with a winter mulch of evergreen boughs or straw, insulating them from freezing winds and temperatures. Read more about winter care of lavender plants.
    • Another option for cold areas is to grow lavender in a pot, keeping it outdoors in the summer and indoors in winter. While indoors, place the pot in a south-facing window with as much light as possible鈥攚ater sparingly, as the plant will be dormant at this time.

Pruning Lavender

In cooler climates: Prune established plants in spring when green leaves start to emerge from the base. Remove about one-third of the top to keep the plant from becoming leggy and bare at the base, but do not cut back into old wood, as it will not regrow.

In warm climates: All pruning can be carried out in autumn.

The flowering stems can be harvested while in bloom or snipped off after the flowers fade to keep the plant tidy.

Types

  • English lavender (Lavandula angustifolia), the most common, is hardy to USDA Zone 5. It’s edible and often blooms twice a season. Hundreds of varieties exist in many colors (white, pink, blue-violet, and purple) and sizes. 
    • 鈥楬颈诲肠辞迟别’: deep purple flowers; silver-gray foliage; compact form
    • 鈥楳耻苍蝉迟别补诲’: violet-blue flowers; dark green foliage; compact form
    • 鈥楳iss Katherine’: deep pink flowers; aromatic foliage; mounding form
  • Lavandins (L. x intermedia)鈥攁 hybrid of English and Portuguese lavender (L. latifolia)鈥攁re generally larger plants that bloom only once yearly, later in the summer.
    • 鈥楶丑别苍辞尘别苍补濒鈥: vigorous variety highly tolerant of heat and humidity; resistant to common root and foliar diseases; long flower spikes
    • 鈥楶谤辞惫别苍肠别鈥: vigorous, long-stemmed variety; very fragrant
  • Spanish lavender (L. stoechas) and French (fringed) lavender (L. dentata) are typically only winter-hardy in Zones 7 to 9.

Harvesting

How to Grow New Lavender from Cuttings

  • Cut following the plant鈥檚 bloom. Choose side shoots for cuttings that have no buds.
  • Cut very low near the root, getting several inches of stem. Gently scrape the skin off the bottom portion of the stem on one side with a knife. Remove foliage on the bottom 2 inches of the stem.
  • Fill a small pot (4 inches or so) with potting mix. Optional: Dip each cutting in the rooting hormone first.
  • Insert bare stem into potting soil. Firm the soil and water in. Cover the whole pot with clear plastic or a polythene bag to create humidity. Place pots in a warm, shaded area.
  • Allow about 3 weeks for roots to appear. (If you tug gently, the root shouldn鈥檛 move.) Then, remove the bag.
  • Water when soil is dry an inch down; feed with 1/4-strength liquid plant fertilizer once a week.
  • After a few weeks, transplant it into a larger pot.

Harvesting Lavender Flowers

Lavender is a wonderful herb for drying. Here鈥檚 how to harvest it:

  • Harvest in the morning hours when the oils are the most concentrated.
  • Snip off stems when about half of the flower buds have opened, cutting the stems as long as possible.
  • Gather them into bundles and secure them with rubber bands.
  • Dry the bundles of lavender by hanging them in a sheltered, cool, dark place with good air circulation.
  • After a few weeks, the flowers will have dried fully and can be shaken gently from the stems into a lidded jar. Store the flowers in a cool, dark place.

Use your dried lavender to make lavender sachets鈥攁 lovely gift. Lavender sachets can help to keep your sheets or towels smelling sweet, repel moths and insects, and even promote a restful night鈥檚 sleep. 

Storing Lavender

Store lavender flowers in a lidded jar somewhere cool and dark, or pop them straight into a sachet to keep towels, sheets, or clothes smelling sweet and to repel moths. If you suffer from insomnia, try inserting the sachets into a pillow so the calming scent can help you drift off to a restful slumber.

Wit and Wisdom

  • Ancient Egyptians used lavender in the embalming process. They wrapped the dead in shrouds that had been soaked in lavender water.
  • The Romans, all the way back in A.D. 77, are documented to have used lavender to repel insects and soothe insect bites. Add a lavender sachet to your towels, sheets, or clothes to repel moths.
  • The herb is also known for its calming effects. If you suffer from insomnia, try slipping a lavender sachet into your pillow. Lavender oil is used to naturally induce sleep.

Cooking Notes

Although edible, lavender should be used sparingly in recipes. The herb has a lovely perfumed flavor, but it can be too strong or bitter if overused. 

The herb is often used in herbes de Provence mixes, and leaves can be chopped and added sparingly to some sauces, shortbread biscuits and baked goods, ice cream, teas, and lemonade. 

See our recipe for lavender scones and honey-lavender syrup, as well as a recipe for making your own lavender-herb tea.

Have two lavender pots , both had beautiful blooms, one suddenly turned all brown just 2 spots of a little green, the other doing ok. Is there anything I can do with/for the brown one. It was beautiful.

It sounds like root rot due to excess water.

Replace the plant; it’s not coming back.

I never use pesticides. Can I use my lavender I have to bake your scones? What is culinary grade lavender? Thanks so much! Always enjoy your articles!

As long you know that your lavender hasn’t been sprayed with chemicals, it’s perfectly fine to use! 鈥淐ulinary-grade鈥 really just means 鈥渉igh-quality鈥 lavender that has a strong scent and flavor.

Does lavender spread?

Hi Kay,
Lavender does not spread like mint, thyme, or oregano. It grows from seed, growing several inches per year, and flowering in it’s third year.

we have an area were we don't get much sun and would love to plant something that has a flower and smells nice.. was hoping a lavender would work .. what do you think?

Hi Maichen,

Lavender does best in full sun, but can be tolerant to some shade. Other plants with nice flowers that do well in shade include bleeding hearts, foxglove, and and lily of the valley.
