An Introduction to Lavender
Few plants are as universally beloved as lavender. With its silvery-green foliage, vibrant purple flower spikes, and intoxicating fragrance, Lavandula has earned a permanent place in gardens, kitchens, and natural health cabinets around the world. It's a plant of remarkable versatility — equally at home in a formal knot garden, a wildflower meadow planting, a window box, or a kitchen shelf.

Choosing the Right Lavender
Not all lavenders are equal in terms of hardiness, fragrance, or appearance. Here's a quick comparison:
| Type | Hardiness | Fragrance | Best Use |
|---|---|---|---|
| English (L. angustifolia) | Hardy (RHS H5) | Sweet, classic | Culinary, dried flowers, borders |
| French (L. stoechas) | Half-hardy | Camphor-like | Containers, milder climates |
| Lavandin (L. x intermedia) | Hardy | Strong, slightly harsh | Essential oil, hedging, large borders |
For most UK and Northern European gardens, English lavender is the best choice — it's the hardiest and has the most pleasant fragrance for culinary and domestic use.
How to Grow Lavender
Position and Soil
Lavender is a Mediterranean plant at heart, and it thrives in conditions that reflect its origins:
- Full sun: At least 6 hours of direct sunlight per day
- Well-drained, poor soil: Rich, fertile soils actually reduce fragrance and cause plants to become floppy
- Avoid waterlogging at all costs: Lavender will quickly rot in wet, heavy clay
If your soil is clay-heavy, improve drainage by incorporating sharp grit, or grow lavender in raised beds or containers with a gritty compost mix.
Planting and Spacing
Plant lavender in spring or early autumn. Space plants 45–60 cm apart for good air circulation. Water in well after planting, but do not overwater thereafter.
Pruning — the Key to Long-Lived Plants
Lavender that is not pruned regularly becomes woody, straggly, and short-lived. Prune twice a year for best results:
- After flowering (late summer): Cut back the flowered stems by about two-thirds
- Early spring: A lighter trim to tidy the plant and encourage bushy new growth
Never cut back into old wood — lavender does not reliably regrow from bare stems.
Uses of Lavender Around the Home
Culinary
Culinary lavender (English lavender only — other species are too harsh) can be used in:
- Baked goods: shortbread, cakes, and scones
- Herbes de Provence spice blend
- Infused honey or syrup for cocktails and desserts
- Savoury dishes: lamb, duck, and grilled vegetables
Use sparingly — lavender is potent and can easily overwhelm a dish.
Aromatherapy and Wellbeing
Lavender essential oil is one of the most studied aromatic compounds for its calming and sleep-supporting properties. Dried lavender sachets placed in drawers or under pillows are a simple, effective way to enjoy its benefits without any special equipment.
Natural Home Freshening
- Place dried bunches in wardrobes to deter moths
- Add dried flowers to homemade candles or soaps
- Infuse in white vinegar for a fragrant, natural cleaning spray
A Plant Worth Knowing
Lavender rewards gardeners generously — with colour, fragrance, wildlife value (it's a magnet for bees and butterflies), and a wealth of practical uses. Whether you grow a single pot on a doorstep or a long lavender hedge bordering a path, it is one of the most satisfying plants to cultivate and live alongside.
