Description

Spanish Broom, is a deciduous, flowering, perennial, shrub, multi-stemmed and sparsely-leaved, growing to 10 feet in height and width. Often grown as an ornamental because of its flowers, it is winter hardy and can be grown in average, dry to medium, well-drained soils in full sun. It cannot grow in the shade. It has good drought tolerance as well as a tolerance for seaside exposure and can grow in poor rocky soils where it has been applied as a riverbank cover.

Spanish Broom is typically found in dry areas, open woodlands, disturbed sites, and along roads in the Mediterranean area. It is primarily grown for its bright yellow flowers and cylindrical green stems with flowers appearing in showy racemes. When the leaves fall away In late spring, summer shoots are covered in profuse fragrant yellow pea-like flowers. In late summer, seed pods mature and burst open, often with an audible crack, spreading seed from the parent plant.

Insects, Diseases, and Other Plant Problems: No known insect or disease problems. It is aggressive due to self-seeding and has been known to escape gardens and naturalize.
