The French lavender is known as Lavandula dentata; the term 'dentata' means "toothed" and refers to the scalloped leaves. It is extremely drought-tolerant and renowned for its use as a popular essential oil, for culinary, cosmetic, and medicinal applications. 

It is famous for its iconic purple blooms with a calming scent and ruffled, serrated leaves; which results in its other common names such as Toothed Lavender or Fringed Lavender.

Native to the Mediterranean climates, the Lavandula dentata was once considered a subspecies of Spanish lavender (Lavandula stoechas), but it is now recognized as a distinct species.

French Lavender can typically grow up to 3 feet tall and spreads 2 feet. Its compact size makes it an excellent choice for borders, containers, or hedges.

The flowers of French Lavenders are its most striking feature. In frost-free, warm climates, they bloom year-round. In areas that receive frost, it blooms from early spring to fall. They appear in mid-summer and are a vibrant purple color with a distinctive "fringed" appearance due to the toothed edges of the petals. Although it is adorned with its famous purple flowers, Lavandula dentata is not as fragrant as English lavender (Lavandula angustifolia).  

How to Water French Lavender 

French Lavender is an extremely drought-tolerant plant that thrives in dry conditions, making it perfect for water-conscious gardeners or those who tend to forget to water their plants from time to time. Due to its adaptability to arid environments, it requires minimal watering, and you'll rarely need to water it unless faced with extreme heat and drought. 

Make sure the soil drains well to prevent root rot. Avoid overwatering, as this can lead to root rot and other problems. When watering Lavandula dentata, provide about 1-2 inches of water per week, either from rain or irrigation. Mulching around the base of the plant with gravel mulch can help retain moisture and reduce evaporation. However, avoid getting water on the leaves or crown to prevent fungal diseases. 

When first planted, new Lavender plants appreciate more frequent watering to establish a strong root system. However, once established, they become highly resistant to drought and require less water. In fact, watering every 2-3 weeks is sufficient until blooms appear, indicating the plant's readiness for more frequent hydration. 

As French Lavender blooms, increase watering to once a week or every 10-14 days to promote healthy growth and maximize flower production. After you pick or deadhead the flower, you can revert to the initial watering schedule. Remember, overwatering can harm your Lavender plant, so it's essential to strike the right balance and respect its love for dry conditions.

Seasonal Watering Needs 

During periods of extreme drought, French Lavender plant may drop its leaves or become dormant to conserve water. Don't worry! With regular watering, it will recover quickly. 

Light Requirements: Where to Put French Lavender 

When growing French Lavender indoors, it's essential to provide it with plenty of bright light to mimic its natural Mediterranean habitat. Place your Lavender plant in a south-facing window that receives direct sunlight for at least 4-6 hours a day.

If this isn't possible, east- or west-facing windows can also work, but avoid north-facing windows as they receive too little light. Supplement with grow lights if necessary to ensure your plant receives the light it needs.

Remember, your plant French lavender Lavandula dentata prefers bright, indirect light. Avoid placing it in a spot with low light, as this can lead to weak and spindly growth. If you're growing it indoors during the winter months, consider moving it to a brighter location or using grow lights to compensate for the shorter days. 

For outdoor cultivation, choose a location that receives full sun to partial shade. French Lavender plants love basking in direct sunlight for 6-8 hours a day, but they can tolerate some shade, especially in warmer climates. If you live in a hot, sunny area, consider providing some afternoon shade to prevent scorching. In cooler, cloudier climates, opt for a sunnier spot to encourage blooming.  

French Lavender’s Perfect Mix: Soil & Fertilizer 

The French lavender prefers well-drained alkaline soil, as excess moisture can promote root and stem rot. Avoid heavy clay or sandy soils, as they can lead to root rot or drought stress. Instead, opt for a mix specifically designed for Mediterranean plants like Lavandula dentata, which typically contains a blend of peat moss, perlite, and vermiculite. Planet Desert has specialized potting soil, opens in a new tab that includes an organic substrate with mycorrhizae to help grow a healthy root system and help your plants thrive. 

In terms of fertilizer, it requires minimal or no feeding. This plant thrives on very few nutrients, whereas too many nutrients can harm the plant, resulting in leggy, yellowed foliage and fewer flowers. 

If your French lavender plants aren't looking their best, nutrient deficiencies could be the cause. A balanced, water-soluble NPK fertilizer applied at half the recommended strength is sufficient. You can fertilize in the spring when new growth appears. 

When choosing a fertilizer for French Lavender, look for one that is high in potassium (K) and low in nitrogen (N). Potassium promotes root growth, flower production, and overall plant health, while excessive nitrogen can lead to weak stems and fewer blooms. A balanced fertilizer with a ratio of 5-10-10 (N-P-K) is suitable for Lavender.

It also benefits from a layer of compost or well-rotted manure around the base, which provides slow-release nutrients and improves soil structure.

Hardiness Zones & More  

When growing indoors, it prefers daytime temperatures between 65°F and 75°F and nighttime temperatures around 55°F. Maintain a consistent temperature, avoiding sudden drops or rises. They prefer relatively low humid climates, around 40-50%. You can achieve this by placing the pot on a tray with pebbles and water or using a humidifier. 

French Lavender can tolerate some fluctuations in temperature and humidity, but extreme conditions can lead to stress and poor growth. Avoid placing your plant near heating or cooling vents, fireplaces, or drafty windows. If you live in a hot and humid climate, consider using an air conditioner or dehumidifier to maintain a suitable environment for your Lavender. 

For outdoor cultivation, it thrives in USDA zones 8-11, meaning it can tolerate temperatures as low as 20°F and as high as 90°F. If you live outside these zones, consider growing French Lavender in containers that can be moved indoors during extreme weather conditions. It prefers full sun and ventilation, making it an excellent choice for gardens with good air circulation. In warmer climates, provide some afternoon shade to prevent scorching. It can tolerate some frost but may need protection during prolonged periods of extreme cold.
