Spanish broom
Spartium junceum, family Fabaceae
A tall shrub with rush-like stems and fragrant yellow flowers
Spanish broom is a deciduous shrub that grows up to 4 metres tall, with sparse leaves and abundant yellow pea-shaped blooms in late spring and summer. Native to the Mediterranean region, it has spread to many parts of the world and is valued ornamentally but also considered invasive in several countries.
- Its stems are rush-like and carry out photosynthesis after leaves fall early.
- Produces fragrant yellow pea-shaped flowers in late spring and summer.
- Considered invasive in California, Chile, Australia, and South Africa.
- All parts contain toxic alkaloids that affect the heart and nervous system.
- Used traditionally for fiber, dye, brooms, and in folk medicine for ulcers.
What does Spanish broom look like?
Spanish broom forms an upright, leafy shrub reaching 2 to 4 metres high. Its green, rush-like stems carry very few small leaves, which drop early. From late spring through summer, clusters of fragrant yellow flowers, each about 1–2 cm wide and shaped like peas, cover the branches. By late summer, long black seed pods split open with a snap, scattering seeds.
Where does Spanish broom come from?
This plant belongs to the legume family and is the only species in its genus. Its name comes from Greek and Latin words referring to its historical use in making rope and its reed-like stems. It originates from the Mediterranean basin, where it thrives in sunny, dry, sandy places.
When and how Spanish broom blooms
It flowers in late spring and summer, producing masses of yellow blooms on green stems that perform most of the plant’s photosynthesis. It grows well in dry, well-drained soils and full sun. Though native to the Mediterranean, it has been planted widely elsewhere as an ornamental and has naturalized in regions with similar climates.
How Spanish broom is used
People grow it in gardens for its showy flowers and use its flexible stems to make brooms and tie vines. The plant yields a yellow dye, fibers for cloth, and an essential oil used in perfumery. In some Andean communities, it is believed to ward off evil. Its flowers are also used in traditional remedies.
What Spanish broom means
In Catalonia, it is known as ginesta and seen as a national symbol, sometimes paired with red poppies. In Peru and Bolivia, called retama, it appears along city streets and features in local song and memory, such as the huayno 'Flor de Retama,' linked to a 1969 tragedy. Afterward, authorities removed the flowers from Huanta’s main square, though they now mark the town’s entrances.
