This plant produces multiple show-stopping bright bi-colored yellow and red flowers along its stems in early spring. It’s the perfect plant to jump-start color in your garden and drive away your winter blues. Sister Disco Scotch Broom is deer resistant and drought and salt tolerant making it a great choice to plant along the road and salt-treated walkways.
This deciduous plant reaches 1 to 3 feet tall and wide at maturity and grows in an upright mounding habit that slightly weeps over. After the flowers fade, the bright tiny green leaves make it an attractive textural shrub for summer and fall interest in your landscape. The seed pods create interest after the leaves have dropped in the fall. Plant Sister Disco® Cytisus scoparius 'SMNCSCRY' USPPAF in a sunny location in USDA hardiness zones 5 to 8.
Sister Disco Scotch Broom Care
Sister Disco Scotch Broom is low to no maintenance and does not need pruning. The flowers appear on old wood so if you do any pruning, make sure to do it soon after the flowers fade to avoid cutting away next year’s blossoms. The flowers can be added to bouquets.
Sister Disco Scotch Broom Spacing
This plant makes a great companion to spring-flowering bulbs because they bloom around the same time. It can be used to create low borders, as a specimen plant, in perennial or shrub gardens and in containers. Space multiple plants 3 feet apart on center. This plant is not recommended for the northwestern US.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
