Spartium junceum: Embracing the Beauty of Spanish Broom

Spartium junceum, commonly known as Spanish Broom, Rush Broom, or Weaver’s Broom, is a captivating medium-sized shrub belonging to the Fabaceae family of plants. It exhibits unique characteristics with its erect broom-like shoots and sparse leaves, relying primarily on photosynthesis through its shoots rather than foliage.

Origins and Distribution:

Spartium junceum is native to the Mediterranean region, Southwest Asia, and Northwest Africa. It thrives in these diverse regions, adapting to a range of environmental conditions. The plant can reach a height of approximately 4 meters or 13 feet, creating an impressive presence in the landscape.


This evergreen shrub boasts thick and succulent shoots, resembling broom handles. The leaves are sparse and play a minor role in the plant’s overall physiology, as the majority of photosynthesis occurs through the shoots. Spartium junceum‘s unique structural adaptation contributes to its remarkable resilience and ability to thrive in poor, well-drained soils.

How to grow Spartium junceum:

To cultivate Spartium junceum successfully, consider the following guidelines:

Light and Soil Requirements: Spanish Broom thrives in full sun exposure, making it ideal for sunny garden spots. It prefers well-drained soil, even in poor or nutrient-deficient conditions. Partial shade is not suitable for this plant’s optimal growth.

Drought and Deer Resistance: Spartium junceum exhibits excellent drought tolerance, making it an ideal choice for water-wise gardens. Additionally, its foliage is unpalatable to deer, reducing the risk of browsing damage.

Flowering and Seed Pods: Spanish Broom delights with its profusion of vibrant yellow, pea-like flowers that adorn the plant in late summer. These cheerful blooms add a splash of color to the landscape. Following the flowering period, Spartium junceum produces seed pods that mature to a striking black color. These pods, reaching a size of approximately 10 centimeters or 4 inches, add visual interest to the plant.

Invasive Potential: It’s important to note that Spartium junceum has become invasive in certain regions, such as California and Oregon. Careful consideration should be given to planting it in these areas, or consult with local gardening authorities for guidance.

Propagation: Propagate Spanish Broom through seed propagation. Collect mature seeds from the pods and sow them in a suitable growing medium or directly in the desired location.

Pests and Diseases:

Spartium junceum is generally disease-free and resistant to common pests. It requires minimal intervention in terms of pest control, adding to its low-maintenance appeal.

Traditional Uses:

Throughout history, Spartium junceum has served various purposes beyond its ornamental value. The plant’s essential oils, extracted from its foliage, are utilized in perfumery and aromatherapy. Additionally, the plant’s fibers have been traditionally used for cloth making, and its flowers have been employed for coloring dyes.


With its distinctive appearance and remarkable adaptability, Spartium junceum, or Spanish Broom, adds a touch of allure to gardens. This medium-sized shrub captivates with its broom-like shoots, yellow flowers, and resilience in challenging growing conditions.
