Moonlight Scotch Broom

Attractive green stems are cloaked with tiny, bright green leaves throughout the summer. Use as a lovely spring specimen or for mass plantings in borders. Deciduous.

Design IdeasPlants with pale yellow flowers, such as this broom, reflect moonlight and look beautiful in gardens for that purpose. Because such subtle coloring can bleach with intense sunlight, this broom may benefit from in a slightly sheltered location in warmer regions. Use as a hedge, individual specimen or a clump that fills corners or blocks unattractive views.
