Understanding English vs French Lavender
When considering lavender for your garden, the primary distinction often lies between what are commonly known as English lavender and French lavender. While both belong to the Lavandula genus and share a delightful fragrance, they possess unique traits that make them suitable for different climates, garden styles, and purposes. Understanding these differences is key to making an informed choice for your planting project.
The most visible difference usually lies in the flower structure. English lavender (Lavandula angustifolia) typically features shorter, more compact flower spikes with a dense arrangement of individual florets. French lavender (Lavandula stoechas), conversely, is recognisable by its distinctive 'bunny ears' or 'flags' – sterile bracts that protrude from the top of the main flower spike, giving it a more elaborate appearance. This visual cue is often the easiest way to differentiate them at a glance.
Beyond appearance, their hardiness and preferred growing conditions vary. English lavender is renowned for its superior cold tolerance, making it a robust choice for regions experiencing harsh winters. French lavender, while beautiful, generally prefers warmer climates and is less tolerant of frost. This fundamental difference in hardiness dictates where each type thrives most successfully, influencing planting decisions significantly.
- English lavender is cold-hardy with compact spikes.
- French lavender has distinctive 'bunny ear' bracts and prefers warmth.
- Variety choice depends on climate, garden aesthetic, and desired use.
- Both require well-drained soil and full sun for optimal growth.
Key Characteristics Compared
The common name 'English lavender' refers to species like Lavandula angustifolia, often called True Lavender. It is prized for its intense, classic lavender scent, making it a favourite for essential oils, sachets, and culinary uses. Its foliage is typically narrow and grey-green. The plant itself is generally more upright and bushy, forming a tidy mound.
French lavender, scientifically known as Lavandula stoechas, is also called Spanish lavender. Its fragrance is often described as less potent or more camphoraceous compared to English lavender. While still aromatic, its primary appeal for many gardeners is its striking visual appeal with those prominent bracts atop the flower heads. The foliage can be broader and darker green.
When you plant lavender, considering these core differences will prevent disappointment. For instance, attempting to grow French lavender outdoors year-round in a region with sub-zero temperatures is likely to fail, whereas English lavender would likely endure. Conversely, in very hot, humid climates, French lavender might perform better than some English varieties.
Fragrance and Uses: Scent Profiles Compared
The aromatic qualities of lavender are central to its appeal, yet the nuanced differences in scent between English and French varieties mean they are often better suited to specific applications. Understanding these scent profiles can help you choose the right lavender for your home or garden.
English lavender, particularly cultivars of Lavandula angustifolia, is the standard-bearer for that universally recognised, sweet, floral, and slightly herbaceous aroma. This characteristic scent is why it is overwhelmingly the preferred choice for producing high-quality essential oils used in aromatherapy, perfumery, and skincare. Its scent is also highly valued in culinary applications, from baked goods to teas, due to its clean, pleasant profile. If you envision using lavender for its classic, calming fragrance or in recipes, English lavender is likely your best bet.
French lavender, Lavandula stoechas, offers a different olfactory experience. Its scent is often more pungent, with stronger notes of camphor and eucalyptus. While still aromatic and enjoyable, it is generally considered less delicate and less suited for culinary purposes. The aroma can be more invigorating or medicinal, making it ideal for potpourri where a stronger, more herbaceous scent is desired, or for natural insect repellents. However, for those seeking the quintessential lavender aroma for relaxation or flavour, French lavender might not fully meet expectations.
Choosing for Scent
When selecting a lavender plant, think about how you intend to use its fragrance. For a relaxing bedroom sachet, a linen spray, or a flavourful addition to desserts, the sweet, classic scent of English lavender is unparalleled. Its essential oil is also widely studied for its calming properties.
If your aim is to create a strongly scented border that also deters pests, or if you prefer a more robust, camphoraceous aroma in your garden, French lavender can be a compelling choice. Its unique scent can add another layer to the sensory experience of a Mediterranean-style garden.
It is worth noting that the intensity of fragrance can also depend on the specific cultivar, growing conditions, and when the flowers are harvested. However, the general distinction between the sweeter, classic scent of English lavender and the more camphoraceous, potent scent of French lavender holds true for most varieties.
Growing Conditions and Hardiness: Garden Suitability
The success of your lavender planting hinges significantly on matching the plant's needs to your local environment. While both English and French lavender thrive in similar conditions regarding sunlight and soil drainage, their tolerance for temperature extremes creates a crucial divergence in their suitability across different climates.
English lavender (Lavandula angustifolia) is exceptionally hardy and is often recommended for gardeners in colder climates. It can typically withstand winter temperatures down to USDA hardiness zones 5 or 6, and sometimes even zone 4 with protection. This robust nature means it can be grown as a perennial in much of the UK and northern Europe. It prefers well-drained, slightly alkaline soil and full sun, ideally 6-8 hours per day. It can tolerate a range of soil types as long as they are not waterlogged, which is the primary cause of lavender death.
French lavender (Lavandula stoechas), on the other hand, is more suited to warmer, milder climates and is generally less cold-tolerant, typically thriving in USDA zones 7 or 8 and above. It can be grown as an annual in cooler regions or overwintered indoors. Like its English counterpart, it demands excellent drainage and full sun. French lavender can sometimes be more sensitive to humidity and may benefit from slightly more air circulation, making it a popular choice for coastal or Mediterranean gardens. When to plant lavender in these warmer zones is less critical than ensuring it has adequate space and sun.
Pruning Lavender for Longevity
Proper pruning is vital for maintaining the health, shape, and flowering vigour of both types of lavender, but the timing and approach can differ slightly. Generally, lavender plants benefit from pruning after their main flowering period and again in early spring.
Pruning English lavender typically involves a light trim after flowering to deadhead spent blooms and encourage a second flush, followed by a more substantial prune in early spring. You should cut back the plant by about one-third to one-half, ensuring you don't cut into old, woody stems, as this can hinder regrowth. This helps maintain a compact shape and prevents the plant from becoming leggy and woody.
Pruning French lavender can be a little more delicate. After flowering, deadhead the spent blooms. A light trim can be done in early spring, similar to English lavender, but it's often advisable to be slightly more conservative with the cut to avoid damaging the plant's structure, especially if it has shown sensitivity to cold. Overgrown French lavender can be more challenging to revive than English varieties.
Protect lavender from waterlogged soil by planting it on a slope, in raised beds, or amending heavy clay soil generously with grit and compost.
When to cut lavender back for both types should also consider your specific climate. In very cold regions, delaying the main spring prune until all danger of hard frost has passed is a prudent measure.
Appearance and Cultivars: Visual Distinctions
Beyond the fundamental differences in bloom structure and hardiness, a wealth of cultivars exists within both English and French lavender, offering gardeners a spectrum of colours, sizes, and subtle variations in appearance. While the core distinctions remain, exploring specific cultivars can help you find the perfect lavender plant for your aesthetic.
English Lavender (Lavandula angustifolia) cultivars are perhaps the most widely recognised and numerous. They are celebrated for their classic, upright flower spikes. Common colours range from deep violet and blue to pink and white. Cultivars like 'Hidcote' are famous for their rich, dark purple blooms and compact growth habit, often remaining smaller and more densely mounded, making them ideal for edging. 'Munstead' is another popular variety, known for its slightly lighter purple flowers and vigorous, slightly more open growth. These varieties generally produce abundant, well-formed flower spikes that are excellent for cutting and drying.
French Lavender (Lavandula stoechas) cultivars are instantly identifiable by their distinctive terminal bracts, which can be bright pink, purple, white, or even a greenish hue, often contrasting with the main flower colour. The flower spikes themselves are typically shorter and thicker than those of English lavender. Cultivars like 'Anouk' series offer vibrant colours and are known for their long flowering season, often blooming multiple times throughout the year in suitable climates. The visual appeal of French lavender is undeniably its showy, almost exotic bloom structure, making it a focal point in the garden.
Foliage and Plant Habit
The foliage of both types is aromatic and typically silvery-green, contributing to the plant's overall visual appeal even when not in bloom. However, subtle differences exist. English lavender foliage tends to be finer and more linear, contributing to a neat, mounded appearance. French lavender foliage can sometimes be broader, and the plant may have a slightly more sprawling or less rigidly upright habit compared to some of the more compact English varieties. This means careful consideration of spacing is important when planting to allow each plant to reach its natural size and shape.
When planning your planting, consider the mature size of the cultivar. Some 'Hidcote lavender plants', for example, will remain quite compact, suitable for smaller gardens or containers, while others, like some 'Munstead' cultivars, might spread wider. Understanding these variations within each type ensures you select plants that will not overcrowd each other and will achieve the desired garden composition.
The allure of lavender lies not just in its scent but in its resilience and adaptability, offering a touch of the Mediterranean to gardens worldwide.
Ultimately, the choice between English and French lavender can come down to personal preference for visual impact. Do you prefer the classic elegance and prolific scent of the English types, or the flamboyant, unique blooms of the French varieties? Both offer significant rewards for the discerning gardener.
Taking Cuttings and Propagation
Both English and French lavender are readily propagated from cuttings, a rewarding process that allows you to expand your collection or share plants with fellow enthusiasts. Knowing how do you take cuttings from lavender plants and the best time to do it can significantly increase your success rate.
The ideal time to take lavender cuttings is generally in late spring or early summer, after the plant has finished its main flowering period. Semi-hardwood cuttings are usually most successful. These are stems that have started to harden but are still somewhat flexible. For both English and French lavender, select healthy, non-flowering shoots from the current season's growth.
How to Take Lavender Cuttings
To take cuttings: Use a clean, sharp knife or secateurs to cut a length of stem, typically 4-6 inches long. Remove the lower leaves from the cutting, leaving just a few at the top. You can then dip the cut end into rooting hormone powder, though this is optional but can speed up the process and improve success rates.
Prepare a pot filled with a well-draining compost mix, often a 50/50 blend of compost and grit or perlite. Make a hole in the compost with a pencil or dibber and insert the cutting, firming the compost gently around it. Water lightly.
Caring for Lavender Cuttings
To encourage root development, it's beneficial to create a humid environment. You can achieve this by covering the pot with a plastic bag, ensuring it doesn't touch the leaves, or by placing the pot in a propagator. Keep the cuttings in a bright spot, but out of direct sunlight. The compost should be kept consistently moist but not waterlogged.
Roots typically begin to form within 4-6 weeks. You can gently tug on a cutting to check for resistance, indicating root formation. Once roots are established, you can carefully transplant the young lavender plants into individual pots. They can be planted out into their final positions in the garden the following spring, after the last frost.
Whether you are growing Lavandula angustifolia or Lavandula stoechas, the process for taking lavender cuttings is largely the same. Patience is key, and providing the right conditions for root development is crucial for turning a simple stem cutting into a thriving lavender plant.
If you're looking to establish an indoor lavender plant, ensuring it receives adequate light and has excellent drainage in its pot is paramount. While lavender generally prefers outdoor conditions, certain compact varieties can be successfully grown indoors with diligent care.
