Lavender plants, celebrated for their soothing fragrance and beautiful blooms, are a popular choice for gardens worldwide. However, not all lavenders are created equal, and understanding the different types is key to providing the best care and ensuring these aromatic plants thrive. Choosing the right variety and knowing its specific needs will lead to a flourishing lavender garden year after year.
Caring for English Lavender
English lavender, botanically known as Lavandula angustifolia, is renowned for its exceptional cold hardiness, making it a favorite in cooler climates. Despite its Mediterranean origins, it earned its name from its successful cultivation in England’s climate. This variety typically features gray-green foliage and charming whorls of small flowers in shades of blue-purple to vibrant violet. Reaching a height of 2-3 feet, English lavender excels in well-draining soil, even sandy conditions, and is suitable for USDA hardiness zones 5-10.
To care for English Lavender:
- Sunlight: Ensure it receives full sun, ideally 6-8 hours daily, for optimal blooming and growth.
- Soil: Plant in well-draining soil. Amend heavy clay soils with compost or other organic matter to improve drainage.
- Watering: Water deeply but infrequently, allowing the soil to dry out between waterings. Overwatering can lead to root rot, especially in poorly draining soils.
- Pruning: Prune annually after flowering to maintain shape and encourage bushier growth. Cut back spent flower spikes and lightly trim foliage.
- Fertilizing: English lavender generally doesn’t require heavy fertilization. A light application of a balanced fertilizer in early spring can be beneficial in nutrient-poor soils.
- Cold Hardiness: Its excellent cold hardiness makes it ideal for cooler climates, but mulching around the base in very cold regions can provide extra protection.

Caring for Hybrid Lavender
Hybrid lavender, or Lavandula x intermedia (Lavandula hybrida), is a robust cross between English and Portuguese lavender, combining the best traits of both. It inherits the cold hardiness of English lavender and the heat tolerance of Portuguese lavender, resulting in a versatile and resilient plant. Hybrid lavender is known for its long, striking spikes of highly fragrant flowers, ranging from deep violet to white, complemented by aromatic gray-green foliage. It thrives in zones 5-11 and is a fantastic choice as a focal point or within herb and rock gardens.
To care for Hybrid Lavender:
- Sunlight: Similar to English lavender, full sun (6-8 hours daily) is crucial for vigorous growth and abundant flowering.
- Soil: Well-draining soil is essential. Ensure good drainage to prevent root issues, especially in wetter climates.
- Watering: Water moderately, allowing the soil to dry slightly between watering sessions. Avoid consistently soggy soil.
- Pruning: Prune more significantly than English lavender after flowering. Cut back about one-third of the plant to maintain shape and encourage new growth. This variety can become quite large if not pruned regularly.
- Fertilizing: Hybrid lavender is not a heavy feeder. A spring application of a slow-release fertilizer or compost is generally sufficient.
- Heat and Cold Tolerance: Its hybrid nature provides good tolerance to both heat and cold, making it adaptable to a wide range of climates within its hardiness zones.

Caring for Other Lavender Varieties: French, Spanish, and Woolly Lavender
While English and Hybrid lavenders are popular for their hardiness and fragrance, other varieties like French, Spanish, and Woolly lavender offer unique characteristics and care considerations. These types are generally less cold-hardy and have specific preferences.
French or Fringed Lavender Care
French lavender (Lavandula dentata), originating from the Mediterranean basin, North Africa, and the Arabian Peninsula, is recognized by its toothed leaves with a distinctive lavender-rosemary scent. It boasts showy, compact flower heads topped with purple bracts and can bloom from early summer to fall in warm, sunny conditions. Although its floral scent is milder than other lavenders, its foliage offers a pleasant rosemary-lavender aroma when crushed.
To care for French Lavender:
- Sunlight: Requires full sun and warmth to thrive and bloom profusely.
- Soil: Prefers well-draining soil but is slightly more adaptable to different soil types than English lavender.
- Watering: Water moderately, allowing the soil surface to dry between waterings. Ensure good drainage, especially in containers.
- Pruning: Light pruning after flowering to remove spent blooms and maintain shape. Avoid heavy pruning into old wood.
- Warmth: French lavender is less cold-hardy (zones 8-9) and thrives in warmer climates. Protect from frost in cooler regions or grow in containers that can be moved indoors.
Spanish Lavender Care
Spanish lavender (Lavandula stoechas) is known for its unique flowers featuring prominent “ears” or bracts atop each flower spike. Blooming almost continuously from mid-spring to late summer in white, pink, and purple hues, Spanish lavender adds long-lasting color to gardens. While its flowers are not intensely fragrant, its silvery foliage emits a noticeable scent. This variety is best suited for warm climates, thriving in hardiness zones 7-9.
To care for Spanish Lavender:
- Sunlight: Full sun is crucial for optimal flowering and foliage color.
- Soil: Well-draining soil is vital. Sandy or gravelly soils are ideal.
- Watering: Drought-tolerant once established. Water sparingly, allowing the soil to dry out thoroughly between waterings. Avoid overwatering.
- Pruning: Prune after each major bloom cycle to encourage continuous flowering and maintain a compact form. Deadheading spent flowers promotes further blooming.
- Warm Climates: Spanish lavender prefers warm climates and may not survive harsh winters. It’s well-suited for Mediterranean-like conditions.
Woolly Lavender Care
Woolly lavender (Lavandula lanata) is a drought-tolerant, bushy shrub native to the Mediterranean. It is characterized by its soft, silver-white, woolly leaves and long stalks topped with purple flowers. Woolly lavender is an excellent choice for rock or gravel gardens and attracts bees and butterflies, enhancing garden biodiversity. Its leaves are highly aromatic and densely hairy, giving them a distinctive white appearance.
To care for Woolly Lavender:
- Sunlight: Requires full sun for best growth and foliage color.
- Soil: Thrives in well-draining, even poor, soils. Excellent for dry, rocky locations.
- Watering: Very drought-tolerant once established. Water sparingly, especially in well-draining soil. Avoid overwatering, which can be detrimental.
- Pruning: Light pruning after flowering to maintain shape and remove spent flower stalks. Avoid heavy pruning.
- Drought Tolerance: Its exceptional drought tolerance makes it ideal for water-wise gardens and dry climates.

By understanding the specific needs of each lavender type, you can provide tailored care that allows them to flourish. Whether you choose the hardy English lavender, the versatile hybrid, or the unique French, Spanish, or Woolly varieties, proper care will reward you with beautiful, fragrant plants that enhance your garden and your senses.
