Sister Disco® Scotch Broom

Discover More Information On Sister Disco® Scotch Broom

The Sister Disco® Scotch Broom (Cytisus scoparius) is a delightful harbinger of spring, boasting vibrant pea-shaped blooms in electrifying yellow accented with splashes of brilliant red. Its strikingly colorful flowers emerge in spring, creating a lively contrast to the green foliage and adding a dramatic flair to gardens, especially when juxtaposed with other spring bloomers like daffodils, tulips, and crocus. Its adaptable nature is apparent in its preference for sunny and dry conditions, making it an ideal companion for spring bulbs. Beyond its dazzling blooms, this Scotch broom offers a distinct textural appeal with its wiry green stems adorned with minuscule leaves. Yet, while it promises to be a showstopper in various landscapes, gardeners in the Northwest should approach with caution as this plant is not recommended for that region.

Beyond its visual allure, the Sister Disco® Scotch Broom is notably hardy, withstanding conditions many plants cannot. It thrives best in full sun, requires minimal maintenance, and is resistant to drought, salt, and the often pesky deer. Its upright habit and broom-like silhouette lend it as an excellent choice for garden beds, landscapes, and as a textural focal point. Furthermore, the Scotch broom's adaptability to poor, well-drained soils ensures it remains resilient even during colder temperatures. However, potential cultivators should be aware of the plant's restrictions; it cannot be shipped to several states due to invasive concerns. When considering the Sister Disco® Scotch Broom for your garden, envision a medium-height shrub that offers not only beauty and texture but also resilience and versatility.

Plant Attributes

One of the most captivating features of the Sister Disco® Scotch Broom is its radiant floral display. In the springtime, gardens graced by this plant come alive with its vivid pea-shaped flowers. The electrifying yellow blooms, accented with bold red touches, present a visual treat that's hard to miss. This chromatic spectacle, when coupled with other spring bloomers like daffodils or tulips, offers a harmonious blend of colors, turning gardens into a painter's palette of vibrant hues.

Beyond its visual charm, the Sister Disco® Scotch Broom is a paragon of resilience. Suited for sunny and dry conditions, it displays a drought-tolerant nature, making it an excellent choice for regions that face water scarcity or areas with well-drained, less fertile soils. This adaptability extends further as the plant showcases salt tolerance, ensuring it remains unfazed in coastal regions or areas with saline soil conditions.

The plant's structural attributes also deserve a special mention. Its upright, broom-like silhouette distinguishes it from many other shrubs, offering a unique textural dimension to garden spaces. After the blooming season, the wiry green stems, populated with minute leaves, provide a textural contrast, making the plant visually appealing year-round.

Landscape Use

  1. Border Highlight: The striking two-toned flowers of the Sister Disco® Scotch Broom make it an excellent choice for garden borders. Its moderate height ensures it doesn't overshadow neighboring plants but still provides a vibrant visual boundary.

Planting & Care


  1. Location Selection: Choose a location that receives full sun for optimal growth. Sister Disco® Scotch Broom thrives in sunny conditions.
  2. Soil Preparation: This plant prefers well-drained soil. If your garden soil retains water, consider amending it with coarse sand or organic matter to improve drainage.
  3. Planting Hole: Dig a hole twice as wide as the plant's root ball and of similar depth.
  4. Planting Depth: Ensure the top of the root ball is level with the ground.
  5. Watering after Planting: Thoroughly water the plant once it's in the ground to help settle the soil and establish the roots.


  1. Watering: Sister Disco® Scotch Broom is drought-tolerant. However, during the initial weeks post-planting, water it regularly to ensure proper establishment. Once established, you can reduce the frequency, especially in regions with regular rainfall.
  2. Fertilizing: This plant does well even in poor soil. However, for richer blooms, you can feed it with a general-purpose slow-release fertilizer in early spring before the new growth starts.
  3. Pruning: Mostly maintenance-free, but if it appears overgrown or unkempt, consider giving it a light trim after it finishes blooming in spring. This helps maintain its shape and encourages denser growth.
  4. Mulching: Apply a layer of mulch around the base of the plant. This retains soil moisture, suppresses weeds, and protects the root system during harsh temperature fluctuations.
  5. Disease and Pest Monitoring: While the Sister Disco® Scotch Broom is quite hardy, it's always good practice to regularly check for signs of diseases or pests and address any issues promptly.
  6. Winter Care: Ensure the soil is well-drained during winter to prevent root rot. The plant is hardy in zones 5 - 8, but in colder areas at the edge of its hardiness range, consider providing some winter protection, like mulch or frost cloth, during extreme cold spells.
  7. Restrictions: Due to concerns about invasiveness, this plant is restricted in some states. Always check local guidelines and regulations before planting.
