Sister Disco Scotch Broom

Sister Disco Scotch Broom (Cytisus scoparius 'SMNCSCRY')

Sister Disco Scotch Broom delivers a bright spring show with two-toned flowers that read as golden yellow with rich red accents. Its compact size makes it easy to place where you want strong color without an oversized shrub taking over the bed. Once established, it handles sun and drier conditions well in sharply drained soil, which helps simplify maintenance in tougher spots. The fine, airy texture keeps borders looking light and layered even when the plant is not in bloom.

Distinctive Features

This scotch broom produces masses of pea-shaped blooms in spring, with yellow petals highlighted by red to orange tones that create a high-contrast look from a distance. Slender green stems and tiny leaves give it a wispy, broom-like texture and a naturally upright to slightly arching habit. The semi-dwarf form stays landscape-friendly while still providing a bold seasonal peak. Mature size is typically about 1 to 3 feet tall and 1 to 3 feet wide.

Growing Conditions

• Sun: Full sun is best for dense growth and the strongest flowering.
• Soil: Plant in sharply well-drained soil, including sandy or gravelly sites, and avoid heavy clay or consistently wet ground.
• Water: Water regularly the first season, then provide occasional deep watering during extended drought once established.
• USDA Zones: Hardy in zones 5 to 8.
• Mature Size: About 1 to 3 feet tall and 1 to 3 feet wide.
• Habit: Upright, compact shrub with fine texture and slightly arching stems.

Ideal Uses

• Focal Point: Use as a focal point where the spring yellow and red flowers can pop against evergreens, stone, or darker foliage.
• Sunny Slopes: Plant on hot, well-drained slopes where sharp drainage and lower watering needs matter.
• Front-of-Border Color: Place near the front of mixed borders to keep the compact bloom show visible and clean.
• Rock and Gravel Gardens: Use in lean, well-drained beds where many flowering shrubs struggle to thrive.
• Container Accent: Grow in a large container with excellent drainage for a bright spring statement on patios and entrances.

Low Maintenance Care

• Pruning: Prune lightly right after flowering to shape and encourage branching, and avoid cutting back into old, leafless wood.
• Watering: Keep soil on the drier side after establishment and avoid frequent shallow watering.
• Fertilizing: Skip heavy feeding, since rich soil can reduce flowering and lead to weak, floppy growth.
• Mulching: Use a light mulch layer to limit weeds while keeping mulch off the crown and stems.
• Drainage: Prioritize sharp drainage to reduce winter moisture stress and root issues.

• Lean-Soil Performer: Thrives in well-drained, lower fertility sites where other shrubs can struggle.
