Getting to Know Lavender: A Plant Profile

Let's get acquainted with this aromatic gem:

• What is it? Lavender belongs to the genus Lavandula, which comprises about 47 known species of flowering plants in the mint family, Lamiaceae (the same family as rosemary, thyme, and basil).

• Appearance:

  • Foliage: Most lavenders have narrow, greyish-green or silvery-grey leaves that are highly aromatic when brushed or crushed. The leaves are typically evergreen or semi-evergreen, depending on the climate.

  • Stems: The stems are often somewhat woody, especially at the base of mature plants, giving them a shrub-like appearance.

  • Growth Habit: Lavender plants typically grow into small, bushy shrubs, ranging in height from 1 to 3 feet (30-90 cm) tall and wide, depending on the variety.

• Lifespan: Lavenders are generally perennials, meaning they live for several years. With proper care, a lavender plant can thrive for many seasons, though some varieties are longer-lived than others.

• Origin: Lavender species are native to the Old World, found from Cape Verde and the Canary Islands, Europe across to northern and eastern Africa, the Mediterranean, southwest Asia to India. The Mediterranean region is particularly famous for its lavender fields.

A Symphony of Purple (and More!): Popular Lavender Varieties

The world of lavender is wonderfully diverse, with different species and cultivars offering variations in flower colour, plant size, fragrance, and hardiness. Here are some of the most popular types for home gardeners:

1. English Lavender 

   • The Classic Choice: This is probably the most well-known and widely grown type, often considered the "true" lavender.

   • Characteristics: Hardy (typically to USDA zone 5), compact, with narrow grey-green leaves and slender spikes of highly fragrant, deep blue-purple, lilac, pink, or white flowers. It has a sweet, classic lavender scent.

   • Blooming Season: Primarily in early to mid-summer.

   • Uses: Excellent for culinary use (flowers and leaves), essential oil production, dried flowers, sachets, and garden borders.

   • Popular Cultivars: 'Hidcote' (deep purple), 'Munstead' (compact, blue-purple), 'Lady' (good from seed), 'Jean Davis' (pink).

2. Lavandin (Lavandula × intermedia):

   • The Robust Hybrid: These are sterile hybrids between English Lavender (L. angustifolia) and Spike Lavender (L. latifolia). They are generally larger, more vigorous, and produce more flower spikes than English lavender.

   • Characteristics: Often grow 2-3 feet tall and wide, with long flower spikes and a strong, somewhat camphoraceous lavender scent (due to the L. latifolia parentage).

   • Blooming Season: Mid to late summer, often a bit later than English lavender.

   • Uses: Primarily grown for their strong fragrance, essential oil (used in perfumes and soaps), and for large-scale dried flower production (wands, bunches). Less preferred for culinary use due to the higher camphor content.

   • Popular Cultivars: 'Grosso' (very fragrant, a major commercial oil producer), 'Provence' (tall, light purple), 'Hidcote Giant'.

3. French Lavender (Lavandula stoechas):

   • Also known as Spanish Lavender or Butterfly Lavender.

   • Characteristics: Distinctive for its pineapple-shaped flower heads topped with prominent, upright petal-like bracts ("rabbit ears" or "wings"). The foliage is often greyish and toothed. It has a strong, piney-lavender scent.

   • Blooming Season: Blooms earlier and often longer than English lavender, typically from spring through summer, sometimes reblooming if deadheaded.

   • Hardiness: Less cold-hardy than English lavender (generally USDA zones 7-9). Often grown as an annual or in containers in colder regions.

   • Uses: Primarily ornamental due to its unique flower shape and strong fragrance. Not typically used for culinary purposes.

   • Popular Cultivars: 'Otto Quast', 'Anouk', 'Kew Red' (pinkish-purple bracts).

4. Fringed Lavender (Lavandula dentata):

   • Characteristics: Named for its finely toothed (dentate) grey-green leaves, which have a rosemary-like fragrance. Produces spikes of pale lavender-blue flowers.

   • Blooming Season: Can bloom nearly year-round in mild climates.

   • Hardiness: Tender perennial (USDA zones 8-9).

   • Uses: Good for hedging in mild climates, fragrant foliage.

When choosing, consider your climate (hardiness zone), the desired fragrance, flower type, and how you intend to use your lavender.

The Signature Spire: What Type of Flower is This Plant?

Lavender flowers are borne on long, slender spikes that rise above the foliage.

• Flower Structure: Each "flower spike" (inflorescence) is actually composed of many tiny individual flowers (florets) arranged in whorls around the stem.

• Flower Shape: The individual florets are small and tubular, typically with two lips, characteristic of the Lamiaceae family.

• Colour: While most famous for its shades of purple and lavender-blue, lavender flowers can also be pink, white, or even deep violet-blue, depending on the species and cultivar.

• Fragrance: The flowers (and leaves) are highly aromatic due to the presence of essential oils, primarily linalool and linalyl acetate. The exact scent profile varies between species, with English lavender being sweet and floral, and Lavandins being more potent and camphoraceous.

• Pollinator Paradise: Lavender flowers are incredibly attractive to bees (especially bumblebees and honeybees), butterflies, and other beneficial insects, making them a fantastic addition to a pollinator-friendly garden.

From Seedling to Scented Shrub: Time to Grow

Growing lavender successfully involves understanding its preferred timeline.

• Starting from Cuttings or Young Plants (Recommended):

  • This is the easiest and most reliable way to grow lavender, especially for specific cultivars, as they will be true to type.

  • Young plants purchased from a nursery can be planted out in spring after the last frost or in early autumn.

  • Cuttings taken from established plants in late spring or early summer can root within 4-6 weeks.

• Starting from Seed:

  • Growing lavender from seed can be a bit more challenging and slower. Germination can be erratic, and seedlings are often slow to establish. Hybrid varieties (like Lavandins) will not come true from seed.

  • When to Sow: Start seeds indoors about 8-10 weeks before your last expected frost date.

  • Seed Sowing: Sow seeds shallowly on the surface of a well-draining seed-starting mix and lightly cover with fine vermiculite or perlite, as some light can aid germination.

  • Germination Conditions: Provide warmth (around 65-70°F or 18-21°C) and consistent moisture. Patience is key. Stratification (a period of cold, moist conditions) can sometimes improve germination for some lavender seeds.

• Growth Rate: Lavender is generally a moderately fast-growing shrub once established.

• Time to Flower:

  • From Young Plants/Cuttings: You may get some flowers in the first year, but the plant will typically establish its root system and produce a more significant bloom in its second year and beyond.

  • From Seed: It will usually take at least one full growing season, often two, for seed-grown lavender to mature enough to flower profusely.

Feeding Your Fragrant Friend: Less is More

One of the most common mistakes with lavender is over-coddling it, especially with fertilizer.

• Soil Preference:

  • Lavender absolutely demands well-draining soil. This is the single most critical factor for success. It thrives in gritty, sandy, or gravelly soils and dislikes "wet feet," which can lead to root rot.

  • It prefers a neutral to slightly alkaline soil pH (around 6.5 to 7.5 or even slightly higher). If your soil is acidic, you may need to amend it with lime.

  • Lean Soil is Best: Lavender generally performs best in relatively lean (low-fertility) soil. Overly rich soil can lead to excessive leafy growth at the expense of flowers and fragrance, and can also make the plants less hardy.

• Fertilizing:

  • Generally Not Needed: In most garden soils, established lavender plants do not require supplemental fertilizing.

  • At Planting Time (Optional): If your soil is very poor, you can amend it with a small amount of compost at planting time to improve structure, but avoid rich manures.

  • Avoid High Nitrogen: High-nitrogen fertilizers are detrimental to lavender, promoting weak, floppy growth and reducing flower production and essential oil concentration.

  • Mulch: A mulch of gravel, pea shingle, or sand around the base of the plants can help improve drainage, suppress weeds, and reflect heat, which lavender appreciates. Avoid organic mulches like bark chips right up against the crown, as they can hold too much moisture.

Weather Preferences: Sun-Drenched and Dry

Lavender hails from sunny, Mediterranean-like climates, and its preferences reflect this origin.

• Sunlight: Lavender needs full sun – at least 6 to 8 hours of direct sunlight per day is essential for healthy growth, abundant flowers, and the best fragrance. Insufficient sun will result in leggy plants and sparse blooming.

• Hot Weather: Once established, lavender is very drought-tolerant and thrives in hot, dry summer conditions.

• Cold Weather & Hardiness:

  • English Lavenders (L. angustifolia) and Lavandins (L. × intermedia) are generally the most cold-hardy, often surviving winters in USDA zones 5-9, provided they have excellent drainage (winter wetness is more damaging than cold for them).

  • French Lavenders (L. stoechas) and Fringed Lavenders (L. dentata) are more tender and are typically hardy only in USDA zones 7/8-9. In colder zones, they are best grown as annuals or in containers that can be overwintered indoors or in a protected spot.

• Humidity: Lavender prefers relatively low humidity. In very humid climates, ensure excellent air circulation around the plants to prevent fungal diseases.

Keeping Trouble Away: Pests and How to Handle Them

Lavender is remarkably pest and disease resistant, thanks in large part to its aromatic oils, which many pests find unappealing. However, a few issues can occasionally arise, usually related to less-than-ideal growing conditions.

• Root Rot/Crown Rot: This is the most common problem and is almost always caused by poorly draining, overly wet soil, especially during winter.

  • Handling: Prevention is paramount! Ensure superb drainage by amending soil with grit or planting in raised beds or on slopes. Avoid overwatering. Plant the crown of the lavender slightly proud of the soil level.

• Fungal Diseases (e.g., Leaf Spot, Botrytis): Can occur in overly humid conditions with poor air circulation.

  • Handling: Ensure good spacing between plants. Prune to improve air circulation within the plant. Water at the base of the plant. Remove any affected foliage.

• Spittlebugs: Sometimes you might see frothy "spit" on lavender stems, caused by spittlebug nymphs.

  • Handling: Usually not a major problem. Can be washed off with a jet of water.

• Rosemary Beetles (in some regions): These colourful beetles can sometimes feed on lavender (as well as rosemary and thyme).

  • Handling: Handpick them off if numbers are small.

• Deer and Rabbits: Generally, lavender is considered deer and rabbit resistant due to its strong fragrance. However, very hungry animals might still nibble on young plants.

The Aromatic Harvest: When and How to Pick Your Lavender

Harvesting lavender is a joy, whether for fresh bouquets, drying, or culinary use.

• When to Harvest Flowers:

  • The best time to harvest lavender for drying and for the most intense fragrance is when the flower spikes are about half to two-thirds open, meaning some florets at the bottom of the spike are open, but those at the tip are still in bud.

  • If harvesting for fresh bouquets, you can cut them when just a few florets are open.

  • Harvest on a dry, sunny morning after the dew has evaporated, as this is when the essential oils are most concentrated.

• How to Harvest Flowers:

  1. Use sharp, clean scissors or pruners.

  2. Gather a bunch of flower stems and cut them just above the leafy part of the plant, leaving some green growth on the stem. Aim to cut long stems if you intend to make bunches.

• Drying Lavender:

  1. Gather the cut stems into small bunches.

  2. Secure the bunches with a rubber band or string.

  3. Hang the bunches upside down in a cool, dark, dry, and well-ventilated place for several weeks until the flowers are completely dry and fall easily from the stems when rubbed.

  4. Once dry, you can gently strip the flowers from the stems to use in sachets, potpourri, or culinary preparations.

• Harvesting Leaves (for culinary use): Lavender leaves can also be used for flavouring, though they are less commonly used than the flowers. They can be snipped fresh as needed.

Pruning: Key to a Long-Lived, Shapely Lavender Plant

Proper pruning is essential for keeping lavender plants healthy, productive, and preventing them from becoming overly woody and straggly.

• When to Prune:

  • Main Pruning: The best time for the main pruning is after flowering has finished in late summer or early autumn. In milder climates, this might be the only pruning needed.

  • Light Spring Tidy-Up (Optional): In colder climates, some gardeners prefer to do a light pruning in early spring, after the worst of the winter weather has passed but before new growth starts vigorously. This involves removing any winter damage and lightly shaping the plant. Avoid cutting back hard into old wood in early spring if you're unsure if it's still alive.

• How to Prune:

  1. For the main post-flowering prune, cut back the flowered stems and about one-third of the leafy green growth.

  2. Crucially, always ensure you leave some green leafy growth below your cuts. Do not cut back into the old, bare wood at the base of the plant, as lavender often does not regrow well from old wood.

  3. Aim to maintain a compact, rounded, bushy shape.

• Rejuvenating Old, Woody Plants: If you have an old, very woody lavender plant, it can be difficult to rejuvenate successfully with hard pruning. It's often better to take cuttings and start with new plants.
