What is Scotch broom?

Scotch broom is a shrub that's native to Europe and grows best in USDA hardiness zones 6a to 8b. It grows to between 4 and 6 feet tall and does best in full sun.

Scotch broom can be either deciduous or evergreen and produces fragrant, golden flowers in the spring and summer. It needs regular but not abundant watering and can be propagated from cuttings or seed.

Scotch broom is considered an invasive weed in some places. All parts of the plant are poisonous, and touching it with bare hands can irritate the skin. Gardeners should put on gloves before handling Scotch broom.
