French Lavender Plant Roots and Stems:
an In-depth Look

Updated: March 29, 2022

French lavender, also known as Lavandula stoechas, is a popular ornamental plant known for its fragrant flowers and attractive foliage. This Mediterranean native plant is commonly grown in gardens and is highly valued for its medicinal properties. In this article, we will take an in-depth look at the roots and stems of the French lavender plant.

The Roots of French Lavender Plant

The root system of the French lavender plant is shallow, but extensive. The roots are fibrous and grow horizontally, spreading out in all directions just below the soil surface. The shallow root system allows the plant to absorb nutrients and water from the topsoil effectively. French lavender can grow well in poor, dry soils because of this root system.

The roots are also important for anchoring the plant in place, especially during windy conditions. However, if the soil is too heavy or poorly drained, the roots can easily rot and cause damage to the plant.

The Stems of French Lavender Plant

The stem of the French lavender plant is woody at its base and becomes green and flexible further up towards the leaves. The stems are square-shaped, with four sides that run parallel to each other. The stem’s surface is covered with fine hairs that give it a rough texture.

The stem is also responsible for transporting water and nutrients from the roots to other parts of the plant. It plays a crucial role in maintaining the plant’s overall structure and rigidity.

During the growing season, French lavender plants produce numerous stems that can reach up to 3 feet tall. These stems are covered with small leaves that grow opposite to each other along their length. The leaves are narrow and elongated, with a gray-green color that complements the flowers’ purple hue.

FAQ Section

How often should I water my French lavender plant?

French lavender plants prefer to grow in soil that’s slightly dry, so it’s best to water them sparingly. Once a week is usually enough, but you should adjust the frequency depending on the weather conditions and your soil type.

How do I prune my French lavender plant?

Pruning is essential to maintain the plant’s shape and promote healthy growth. Prune your French lavender plant in late spring or early summer when new growth appears. Use sharp scissors or pruning shears to cut back about one-third of the plant’s total height, being careful not to cut into old wood.

How do I propagate French lavender?

You can propagate French lavender by taking cuttings from established plants. Cut 3-4 inch-long stem sections below a leaf node, and remove the leaves from the bottom half of the stem. Dip the cut end in rooting hormone powder and plant it in a well-draining potting mix. Keep the soil moist and warm, and within a few weeks, you should see new roots and leaves sprouting.

Can I grow French lavender indoors?

French lavender prefers to grow outdoors in full sunlight and well-draining soil. However, you can grow it indoors if you provide enough light and proper airflow. Place your plant near a sunny window, and ensure that the room is well-ventilated to prevent fungal diseases.


In conclusion, French lavender plants have shallow fibrous roots that allow them to grow well in poor soils. The woody base of their stems provides structure and rigidity, while the green parts transport nutrients and water throughout the plant. Knowing how to care for these essential parts of the plant can help you maintain their health and beauty for many years to come.
