french lavender tree French Lavender (Lavandula Dentata)

Mediterranean Beauty That Blooms from Spring Through Fall

French lavender gives your garden months of fragrant purple blooms, often flowering from May through September and continuing into late fall or even year round in warmer climates.

Known scientifically as Lavandula dentata, this evergreen perennial shrub is native to the Mediterranean and prized for long-lasting blooms, scalloped gray green leaves, and a robust herbal scent. Where many lavender plants flower briefly in early summer, French lavender blooms through much of the growing season, helping fill borders, containers, and dry garden spaces with color, texture, and pollinator activity.

Why You’ll Love It

• Extended Blooming Season – French lavender commonly blooms from May through September, with French lavender blooms continuing from early spring through autumn in warm climates and sometimes year round in frost-free areas.

• Drought Tolerant – This drought tolerant french lavender plant thrives in dry California conditions and established plants typically need water only every few weeks unless extreme heat and drought persist.

• Pest Resistant – Aromatic oils in the foliage help repel mosquitoes and other common garden pests, while the lavender flowers still attract bees, butterflies, and other pollinators.

• Larger Size – French lavender reaches a height of 2 to 3 feet and a width of up to 4 feet, with a typical landscape size around 30 inches tall and 40 inches wide for strong garden presence.

• Easy Care – French lavender thrives in dry, well-draining, alkaline soil and actually prefers poor soil conditions, since nutrient-rich, fertile soils can reduce blooming success.

French lavender is excellent for ornamental landscaping because of its dense growth, long bloom period, and airy short spikes of lighter pink-purple flowers. The flower petals and purple flowers bring a softer look than many darker english lavender varieties, while the scalloped foliage keeps the plant attractive even between new blooms.

What Makes It Different

Most lavender varieties have a shorter bloom window, especially English lavender. French lavender provides gardeners with purple blooms, fragrance, and structure for months instead of weeks.

• Longer Blooming Period – French lavender blooms from May through late fall in warmer climates, while English lavender typically blooms for about four weeks starting in mid-June. That makes French lavender a more prolific bloomer during the growing season.

• Heat Tolerance – French lavender prefers warm climates and full sun, making it a strong choice for California yards, Mediterranean gardens, xeriscaping, and dry outdoor borders where other plants may wilt, especially when paired with other drought-tolerant flowering plants like purple bougainvillea.

• Unique Scalloped Leaves – Lavandula dentata is prized for uniquely toothed, gray-green foliage. French lavender flowers are usually lighter pink-purple, while English lavender (Lavandula angustifolia) typically has darker purple flowers and a stronger, sweeter fragrance.

French lavender is often compared to English lavender (Lavandula angustifolia), which is more cold-hardy and primarily used in culinary dishes. English lavender is more cold-hardy, thriving in USDA zones 5-8, while French lavender prefers warmer climates, typically found in USDA zones 7-9, and has a shorter lifespan of about five years compared to English lavender’s potential 15 years.

Its scent is also different. French lavender has a robust, herbal, and slightly camphoraceous aroma. The scent of French lavender is intense and camphoraceous, making it popular for soaps and cleaning products, while essential oils derived from French lavender are valued for their stress-reducing properties and promoting restful sleep. It can also be used in culinary applications such as herbal teas, savory rubs, and infused sugars.

How To Grow French Lavender Successfully

1. Plant in Full Sun Choose a full sun location with 6+ hours of direct sun daily. Plant in well drained soil with sand or sandy loam if possible, and avoid low ground where water collects.

2. Water Sparingly Once established, French lavender is extremely drought-tolerant. Water sparingly, allow soil to dry between waterings, and avoid keeping the soil moist for long periods, since poor drainage can cause root rot.

3. Prune for Shape and New Blooms Pruning French lavender is essential for maintaining its shape. Prune in the fall in mild winter regions, or at the end of winter into early spring after the last frost in colder areas. To encourage more blooms, deadhead spent flowers and occasionally prune French lavender throughout the blooming season.

Good drainage, light watering, and regular deadheading are the key habits that help this lovely plant thrive outdoors in a pot, containers, borders, or a dry Mediterranean yard.
