Comparing Spanish Lavender vs. French Lavender

The 4 Key Differences Between French Lavender and Spanish Lavender

The main difference between French and Spanish lavender is the appearance of their leaves. Spanish lavender has straight leaves, while French lavender has leaves with “toothed” edges. The other differences between these two lavenders include their size, the color of their flowers, when they bloom, and how well they tolerate the cold. There is often some confusion between Spanish and French lavender because they look so similar, but this is often exacerbated by how they sometimes go by different names depending on their country. Spanish lavender (Lavandula stoechas) tends to go by the name “French lavender” in the UK, while outside that country, it goes by Spanish lavender.

French Lavender vs. Spanish Lavender: Size

One of the main differences between French and Spanish lavender is their size. Spanish lavender grows to a height of between 12 and 18 inches and a width of 18 to 24 inches. However, French lavender is much larger and bushier. It reaches 3 feet tall and can spread to an impressive width of 5 feet.

French Lavender vs. Spanish Lavender: Leaves

The most noticeable difference between French and Spanish lavender and one of the easiest ways to tell the two plants apart is the appearance of their leaves. Both are evergreen, so their leaves remain green throughout the year. Spanish lavender has straight, narrow leaves which are 0.4 to 1.4 inches long. However, French lavender has narrow leaves with toothed edges. This is where French lavender gets its scientific name, as dentata literally means “toothed.”

French Lavender vs. Spanish Lavender: Flowers

Another difference between these two plants is the appearance of their flowers and when they appear. Spanish lavender flowers are produced on the top of leafless stems. They appear as a distinctive dense, cylindrical flowerhead topped by petals in a noticeably upright position. Spanish lavender blooms in spring and early summer with brilliant pink to purple colored flowers. French lavender blooms mid to late summer and produces stunning lilac purple flowers. They are produced on short, narrow spikes on leafless stems. French lavender develops small flowers up the flower spike and is topped with larger petals at the top. Although this may seem somewhat similar to Spanish lavender, the noticeable difference comes in the size of the petals in the upper portion of the flower spike and the absence of the small flowers up the spike of Spanish lavender.

French Lavender vs. Spanish Lavender: Cold Tolerance

The final difference between Spanish and French lavender is their cold tolerance. French lavender is not particularly hardy and thrives best in zones 8 to 9. However, it needs to be protected from excessive wet weather during the winter. Spanish lavender is slightly hardier than French lavender and is suited to zones 7 to 9. Anything colder than this puts it at serious risk of dying during the winter.
