Key Facts
- Member of the lavender genus prized for aromatic flower spikes
- Native to the western Mediterranean region
- Prefers full sun and very well drained soils
- Flowers in summer producing grey green foliage and long flower spikes
- Commonly propagated by semi-ripe cuttings and by seed
- Tolerates poor, rocky soils but dislikes winter wet
- Used in drying, fragrance and pollinator plantings
- Generally considered low maintenance once established
Broadleaf Lavender is a Mediterranean lavender prized for long aromatic flower spikes and grey green foliage. It blooms in summer and works well in sunny, well drained beds where fragrance and pollinator value are desired but winter wet must be avoided.
Identification
Lavandula latifolia forms a low woody shrub about 24 to 36 inches tall and wide at maturity. Leaves are grey green and aromatic when crushed and flowers appear as long, scentful spikes in summer, making the plant easy to spot in mixed herb and pollinator plantings.
Where to grow and best uses
Plant Broadleaf Lavender in full sun in rock gardens, Mediterranean borders, or pollinator strips where soil drains quickly. It is commonly used for drying and fragrance because of its long flower spikes, and it fits well at the front of sunny beds or along paths where scent and bees are welcome.
Planting and spacing
Set plants in very well drained sandy or rocky soil and avoid sites that stay wet over winter. Space plants roughly 24 to 36 inches apart to match the mature spread and allow airflow. In heavy soils use raised beds or amend the planting area to improve drainage to reduce the risk of root problems.
Watering and soil
Broadleaf Lavender tolerates poor fertility but dislikes winter wet and poorly drained soils which lead to root rot. Water young plants until established, then reduce frequency and let soil dry between waterings for a compact habit and best flowering. Neutral to alkaline pH suits the species.
After flowering care
Cut back spent flower spikes and lightly shape the plant to keep a compact form and to reduce the chance of becoming woody. Avoid heavy pruning into old wood as this can slow recovery. Plants are generally low maintenance once established when sited in full sun and free draining soil.
Propagation
Propagate Broadleaf Lavender from semi ripe cuttings in late spring or summer for true to type plants. Seed will produce more variable results. Layering and occasional division are possible but can stress the shrub, so cuttings remain the fastest reliable method for gardeners.
Toxicity and impact
Common lavenders are generally regarded as low toxicity for people and pets but ingestion can cause mild stomach upset and concentrated essential oils can irritate skin and mucous membranes. Check ASPCA or local poison control for exact guidance before using essential oils around pets or children.
Frequently asked questions
- How fast does Broadleaf Lavender grow?
- Growth is moderate and plants typically reach about 24 to 36 inches tall and wide when mature, depending on site and care.
- When does Broadleaf Lavender bloom?
- It flowers in summer with long aromatic spikes, often from June through August in the northern hemisphere, though exact months vary by climate.
- What USDA zones will it grow in?
- Broadleaf Lavender is commonly grown in USDA zones 6 to 9 with medium confidence. Extra winter protection may be needed in colder areas and very warm areas can alter flowering rhythm.
- How should I water Broadleaf Lavender?
- Water regularly until established then allow the soil to dry between waterings. Avoid winter wet which leads to root rot in poorly drained soils.
- What is the best propagation method?
- Semi ripe cuttings taken in late spring or summer root reliably and produce true to type plants. Seed is an option but produces more variable offspring.
