Is Lavender Related to Rosemary? The Surprising Truth About These Two Herbs

Lavender and rosemary are two of the most popular herbs in the world. They are widely used for their culinary, medicinal, and aromatic properties. But are they related? And what are the main differences and similarities between them? In this article, we will explore the fascinating facts about these two herbs and answer the question: is lavender related to rosemary?

The Botanical Connection

The first thing to know is that lavender and rosemary are both members of the mint family (Lamiaceae), which includes many other herbs such as basil, mint, thyme, and oregano. This means that they share some common characteristics, such as having square stems, opposite leaves, and flowers arranged in spikes or whorls.

However, being in the same family does not mean that they are closely related. In fact, lavender and rosemary belong to different genera within the mint family. Lavender belongs to the genus Lavandula, which has about 47 species of flowering plants. Rosemary belongs to the genus Rosmarinus, which has only two species: Rosmarinus officinalis (common rosemary) and Rosmarinus eriocalyx (desert rosemary).

Therefore, lavender and rosemary are not very closely related botanically. They are more like distant cousins than siblings.

The Physical Differences

Another way to tell apart lavender and rosemary is by looking at their physical features. Although they have some similarities, such as being evergreen shrubs that can grow up to 6 feet tall, they also have many differences.


One of the most noticeable differences is in their leaves. Rosemary has long, narrow, needle-like leaves that are dark green on top and silver on the underside. They are thick and waxy, with a pine-like aroma when crushed.

Lavender has slender leaves that are covered with fine, soft hairs that give them a fuzzy texture. They are usually green or grayish-green in color, and have a sweet, floral scent when crushed.


Another difference is in their flowers. Rosemary produces small, tubular flowers that range from white to pale blue or pink. They grow in clusters at the end of the stems and have two lips, with the upper lip divided into two lobes and the lower lip having three lobes.

Lavender produces larger, more showy flowers that are usually purple or violet in color. They also grow in spikes at the end of the stems, but have four petals that form a tube with a long upper lip and a short lower lip.
